Irrlicht Engine

Thanks for the help. I actually tried to respond yesterday but I kept getting an error when I tried to log in.

I am trying to get the number of materials on a mesh before creating a scene node from it. How would I do this?

I am using it in 2D. I will look at my code to see if you method will work better. My current solution has worked on all the triangles I have tried it with but I probably need a more thorough test to ensure any solution I go with covers every case.

I am a little surprised that nobody else has had ...

My main project, RCBasic, is still using irrlicht. I just put out a new release a few minutes ago.

Thanks. The main thing I needed to know which you answered is that they should be clockwise. I modified my code to sort them into clockwise order.

void rc_drawTriangle(double x1, double y1, double x2, double y2, double x3, double y3)
{
irr::core::array<irr::video::S3DVertex> v;
v.push_back(video ...

I think I solved it by sorting by the X position in descending order. I don't know whether my solution is a fluke or not but it seems to be working for everything I have tried so far.

I have a function thats suppose to draw a solid color triangle but nothing gets drawn. I tried it with and without array.sort() and it still gives me inconsistent resutls. It will draw if I change the order of the indices but the order seems to be different for different vertices so I am not sure ...

I am away from my development pc for the next week so I can't test mult-texture materials right now. If you are having that issue then I might end up having that issue myself. I am glad to see that my suggestion did give you some good results.

I want to test this out myself when I get back. I would ...

I was having an issue with textures not rendering on a model and I fixed it by disabling the use mishaps flag on the scene node.

It looks like you did this with the IImage rather than using a texture target. I should have looked at the IImage documentation more.

Thanks. I think this is exactly what I needed.

I have been trying to find a way to load images with sizes that are not powers of 2. I tried to have a texture target that is the next higher power of 2 and draw the image to that but the alpha on the image gets applied to a black background on the texture, even if I set the clear color to 0.

Is ...

If you download RCBasic, make sure its v4.x. As of this post, the latest version is v4.10.

These are editors that I bundle with RCBasic. You can dowload that and run Nirvana2D or Serenity3D to see them already built.

It would be more useful if it supported the OpenGL driver. GTK4 supports drawing with OpenGL. https://docs.gtk.org/gtk4/class.GLArea.html . To me, it seems possible to somehow give Irrlicht the GL context so it can do its thing on the GTK.GLArea. I don't know anything about programming with OpenGL ...

Congratulations on the achievement. I also chose irrlicht because I didn't have to work on a 3D engine myself. You and all the developers that have contributed to irrlicht over the years have done some incredible work. I appreciate the work that you have put in to make irrlicht as great as it is.
