Hi.
First of all I’m new to j3d and these forums, so a big hello to anyone that reads this!
Now, my first j3d problem…I’ve noticed that my untextued objects render really fast, but when I add a texture (even to a single tri) then the frame rate drops below 1fps.
I figure this is something to do with the way I’m loading the textures and setting up the appearance (as the sample code didn’t work for me), as other applets with textures seem to work fine so i’ve ruled out a vm/video card/driver problem.
If i use code from the samples e.g.:
TextureLoader loader = new TextureLoader(“bob.gif”, 0, myApplet);
ImageComponent2D image = loader.getImage();
Texture2D texture = new Texture2D();
texture.setImage(0, image);
Then i get an exception on the last line when setting the image…
java.lang.IllegalArgumentException: cannot set image in default texture
at javax.media.j3d.TextureRetained.initImage(TextureRetained.java:335)
at javax.media.j3d.Texture.setImage
If i use something like:
TextureLoader loader = new TextureLoader(“bob.gif”, 0, myApplet);
Texture2D texture = (Texture2D)loader.getTexture();
and then use and modify this texture e.g.
if (texture != null) {
texture.setBoundaryColor(1.0f,1.0f,1.0f,1.0f);
texture.setBoundaryModeS(boundaryModeS);
texture.setBoundaryModeT(boundaryModeT);
texture.setEnable(enable);
texture.setMagFilter(magFilter);
texture.setMinFilter(minFilter);
texture.setMipMapMode(mipMapMode);
myAppearance.setTexture(texture);
}
Then it renders with the texture, but goes very, very slow.
The texture is only 32x32 pixels btw.
I’m hoping this is to do with the dodgy way I’m loading and using the texture but any idea why I can’t get it to work?
Many Thanks
