Port to Winform and SharpGL?
tingspain wrote at 2013-04-25 02:55:
First of all, I would like to say that GREAT JOB. I have checked the demo apps and it is very impresive work.
I was wondering if it is possible to easy port this library to Winform and SharpGL?
I dont know too much about WPF.
Thanks in advance.

Sorry, there are no plans to port to Windows forms and OpenGL.

I looked around very fast the source code of Helix 3D toolkit, and I found get my lest a little lost. I am not familiar with WPF. Do you think that it will be very hard to port to Winform + SharpGL or SharlpDX?
Maybe I can start the porting the code.

Does the architecture make sense in terms of Helix?
objo wrote at 2013-06-18 22:20:
I think performance is important for the mesh generating code. I think this means that platform specific data types (e.g. point, quaternions, transformations) should be used as much as possible, but it is possible that the platform specific data types do not need to be exposed in the public interfaces.

namespace ExtensionMethods
{
public static class MyExtensions
{
public static int WordCount(this String str)
{
return str.Split(new char[] { ' ', '.', '?' },
StringSplitOptions.RemoveEmptyEntries).Length;
}
}
}using ExtensionMethods and:string s = "Hello Extension Methods";
int i = s.WordCount();What strikes me as interesting is that almost every 3D implementation uses a unique type name for its points, quaternions, and transformations, but the actual structure of the structs or class data have to be identical or nearly so. For games, performance of mesh generators is not vital; under the only architectures I can think of, most of those are loaded or preloaded before a high framerate is needed in the game. For engineering use cases, a high triangle count plus a relatively low framerate (mouse gesture animations, mostly) are the order of the day.
Frankly, for most mesh generation, I'm writing my own code against my data models and emitting the WPF formatted arrays and assigning them to the various Visual3Ds I use from the Helix library. So what I'm thinking about is extension methods like "ToOpenGL--structure--" or "ToSharpDX--whatever--" which would take the WPF structures native to Helix and emit the ones compatible with the other libraries. With a modern i5 or i7 and TPL it wouldn't even be computationally time consuming to execute such functions unless the facet counts were in the millions.
For my engineering based low-frame-rate, medium-delay-tolerant use cases, such an approach would not be so bad. I may give this more thought; the OpenTk stuff looks very, very compelling for non-WPF reasons.
Manipulators in code
ChrisKerridge wrote at 2012-04-30 10:52:
First off, great toolkit.
I want to be able to dynamically add objects to a 3D scene and be able to move them with manipulators using code similar to:
var builder = new MeshBuilder(true, true); var position = new Point3D(0, 0, 0); builder.AddSphere(position, 1); var geom = new GeometryModel3D(builder.ToMesh(), Materials.Red); var visual = new ModelVisual3D(); visual.Content = geom; var manipulator = new TranslateManipulator(); manipulator.Bind(visual); manipulator.Position = position; manipulator.Direction = new Vector3D(0, 0, 1); manipulator.Offset = new Vector3D(0, 0, 1); manipulator.Color = Colors.Blue; vp.Children.Add(manipulator); vp.Children.Add(visual);
This gives me a sphere and an arrow pointing upwards (great), but dragging the arrow up and down has no affect on the sphere. How can I get the manipulator to affect the sphere?
Thanks a lot
objo wrote at 2012-05-02 21:36:
I found a bug in the code - the Manipulator.Bind method should not use CombinedManipulator.TargetTransformProperty, but its own. I will submit the fix soon. Thanks for providing the code that made it easy to find the error.
Also, move your code line
manipulator.Bind(visual);
Sorry there is no more documentation than the XML comments and the example on these features - it was experimental code that seemed to work well, so I just put it into the library...

LinesVisual3D Aren't Rendering
jrhokie1 wrote at 2013-01-24 15:09:
I have a WPF app, with my HelixViewport3D's ModelVisual3D Content property bound to a Model3DGroup-type property. I create some EllipsoidVisual3D objects, and add them to my model group by
modelGroup.Children.Add(ev3.Model);
Now I want to create some line segments. I do this
LinesVisual3D lv3d = new LinesVisual3D();
Point3D p1 = new Point3D(...);
lv3d.Points.Add(p1);
Point3D p2 = new Point3D(...);
lv3d.Points.Add(p2);
lv3d.Thickness = 20;
modelGroup.Children.Add(lv3d.Content);
But my lines aren't visible. Setting IsRendering to true doesn't help.
I'm doing MVVM, so I don't want to directly add a visual to my viewport, as is done in the Points and Lines sample. I know I'm using it wrong, I just can't figure out where. Any help will be appreciated.
Thanks.

objo wrote at 2013-02-05 08:55:
Regarding the code - it seems like you are 'stealing' the Model3D from the LinesVisual3D instance. The screen space visuals must be updated every time the camera or transforms are changed, currently this is handled by the CompositionTarget.Rendering event. I guess there was no updating going on in your case where you had disconnected the LinesVisual3D from the visual tree.
Billboard rendering problem

Is is possible to get this type of view from your VRML importer? In MeshLab, this view is obtained by clicking the "WireFrame" button.
glgweeke wrote at 2012-12-04 18:39:
Hi,
in WPF it is not possible to draw a real line in 3D.
Your .WRL-File is using IndexedLineSet which need this feature.
This Helix-Toolkit creates a line with 2 Triangles which what a real size. Not only one pixel on every viewpoint.
To do what you like,
pease patch the following to lines in the VRMLReader.cs file.
1.) Line 734:
if (FindNode("IndexedFaceSet"))
replace
if (false)
2.) Line 949:
mesh.Positions = lg.CreatePositions(linePoints, 0.001);
replace
mesh.Positions = lg.CreatePositions(linePoints, 0.1);
This importer is not stable not finished and not perfect.
PointsVisual3D different Point Colors
Dave_evaD wrote at 2012-10-01 18:20:
Hi,
i have a PointsVisual3D object and I would like to use different colors for the points. As objo mentioned in this post, creating different materials (by creating different PointsVisual3D subobjects) for each point is too slow in rendering. But I don't understand what objo means by "This only supports a single color, but can be extended to support a material containing a 'palette' of colors (then you can set different colors for each point by texture coordinates)." Could you explain it to me or give me an example?
Kind regards, Dave_evaD
govert wrote at 2012-10-01 21:36:
I have some pieces that might get you started:
You can create a small bitmap with one row of colors, maybe like this:
// Creates a bitmap that has a single row containing single pixels with the given colors. // At most 256 colors. public static BitmapSource GetColorsBitmap(IList<Color> colors) { if (colors == null) throw new ArgumentNullException("colors"); if (colors.Count > 256) throw new ArgumentOutOfRangeException("More than 256 colors"); int size = colors.Count; for (int j = colors.Count; j < 256; j++) { colors.Add(Colors.White); } var palette = new BitmapPalette(colors); byte[] pixels = new byte[size]; for (int i = 0; i < size; i++) { pixels[i] = (byte)i; } var bm = BitmapSource.Create(size, 1, 96, 96, PixelFormats.Indexed8, palette, pixels, 1 * size); bm.Freeze(); return bm; }
Then your model might use this Bitmap as its Brush (only two colors used here):
BitmapSource bm = Mesh3DUtil.GetColorsBitmap(new List<Color> { BaseColor, SelectedColor }); ImageBrush ib = new ImageBrush(bm) { ViewportUnits = BrushMappingMode.Absolute, Viewport = new Rect(0, 0, 1, 1) }; // Matches the pixels in the bitmap. GeometryModel3D model = new GeometryModel3D() { Geometry = mesh, Material = new DiffuseMaterial(ib) };
And then for the TextureCoordinates you pick points halfway along the Bitmap:
mesh.TextureCoordinates.Add(new Point(0.5, 0.5));
This is for each little mesh of triangles that forms the little sphere for a point.
Dave_evaD wrote at 2012-10-01 22:00:
Hi govert,
thank you for your reply. I think I've finally understood what the ImageBrush idea is about. But there remains a problem:
As far as I see, I can't set the material/brush for the PointsVisual3D object since it is set in a private method in ScreenSpaceVisual3D. Furthermore I can't access the TextureCoordinates.
Looks like I have to modify the code a bit. I hope the license allows that ;)
Dave_evaD wrote at 2012-10-02 23:21:
Hi govert,
is there a way to use more than 256 colors? I've found nothing for an ImageBrush, what about a BitmapCacheBrush?
govert wrote at 2012-10-02 23:37:
The 256 color limitation might just be a result of the PixelFormat I chose in the BitmapSource.Create call. So if you pick another PixelFormat it might work with more colors. I don't think it has anything to do with the ImageBrush itself. I don't know anything about BitmapCacheBrush, but that seems like a performance optimisation.
This was done a few years ago, though, and I remember that getting the Bitmap and the colors to work right was rather fiddly. You have to get into this stuff a bit: http://msdn.microsoft.com/en-us/magazine/cc534995.aspx.
Dave_evaD wrote at 2012-10-02 23:53:
I tried changing the PixelFormat but the restriction comes from the BitmapPalette. Here's what I found out up to now:
You could use a Brush that draws an ImageSource or a Visual.
If you want to use the ImageSource, you have certain possibilities:
-You could draw a Drawing which offers the possibility to draw an ImageSource (among others which I don't think about that they will be useful)
-You could draw a Direct3D image which does not seem to be what I want
-You could draw a BitmapSource (which has certain subtypes as shown in your link). But each of them has a BitmapPalette which is restricted to 256 colors
If you want to use a Visual, you also have different options:
-A Viewport3DVisual does not seem to be the right thing
-You can draw a Drawing which results in drawing an ImageSource
-You can draw a UIElement. Maybe I could use a Canvas on which I have drawn an Image before, but I wonder whether there is no way to use an Image or Bitmap (not BitmapSource) directly?
govert wrote at 2012-10-03 00:12:
I don't think you have to use an indexed Bitmap format with a fixed palette. You should be able to use one of the other Bitmap formats which give the color of each pixel ? I'd expect WPF to handle most of these formats fine when used with an ImageBrush. You just have to figure out how to encode the actual Bitmap data - maybe first make some bitmaps in Paint or something, and see if you can map those colors into TextureCoordinates.
Dave_evaD wrote at 2012-10-03 00:50:
Hi,
you were right, I realized that I didn't have to use the palette. I use the Bgra32-Format now.
Thanks for your tips.

Automatically move manipulator

DataTemplate3D for custom ModelVisual3D Xml/View
I am studying the WPF DataTemplate example, and it is interesting, data template acts as a kind of bridge into the 3D model?
I'm not sure what CreateItem is all about, except possibly a convention integrating with the sister ItemsVisual3D?
I wouldn't have such a thing in my model. In fact, I'm not sure I would potentially have one data template per model in the view, the content of which is the view instance?
It's making some sense grasping the connecting tissue.
Thank you...
How to render grass and chalk lines easily
I am taking a look at some options how to render grass, for instance as a texture, overlaid on a model, like a RectangleVisual3D and/or polygonal-surface, for instance, then in such a way that I can also render chalk lines, identify some material, etc, that simulates chalk lines, in both lines (or small rectangles themselves), and for font-materials (if there were such a thing? haven't done the research there, yet...).
I've found some tutorials how to work through apps like Paint.NET, GIMP, etc, in order to crank out some grass textures. Basically what's I would consider low to low/medium end quality. Not really looking for medium/high to high end quality at this point for this purpose, nothing even remotely like a Cinema 4D, for instance.
I am also taking a look at Unity3D for potential options there, they can generate grass, but this looks more like a full-fledged game-style development environment. Which might be along the lines what I'd like to do, especially with simulation for sprites, physics, etc. I'm not positive, SharpDX an analog to Unity3D, but it came up looking for grass and related effects.
Anyhow, for now, looking for the configuration aspects and what I can accomplish with a simpler-generated model.
Thank you...
Best regards,
