hello,
  I am programming a Rubic's cube by JPCT based on the "HelloShader" example. I have 27 cubes and I set the shader to each of them. The issue is that on HTC it performs well and on Samsung Galax III it doesn't. After that I tested the example on both of the mobiles, it just worked so fine!Why can this be?

it's solved. thanks.

hello.

I downloaded both "bones" and the android demo, imported them to eclipse. And then I clean the demo project and run. Errors appeared.

Please help.Thanks.

128 * 128 vertices. Every 3 nearest vertices construct a triangle.

33 thousand polygons. Is it strange?
I tried to use Texture Matrix but I don't know how it worked at all.
I searched Texturematrix on this forum and google, nothing helpful things were found.
Can you give me some advice?

I have noticed that. Only 1 fps by using Pologon Manager. I'll try the texture matrix.Thank you.

it seems like i can use polygon manager to solve the problem, but after i used the api "polyManager.setPolygonTexture(p, textInfo);" , nothing happened.

any idea? thanks.

hello!  I am now working on a project which needs the water wave  effect.
I wonder how to modify the uvs after I create a object3D with the uv sequence, use the api like this
obj = new Object3D(vertices, uvs, indices, TextureManager.getInstance().getTextureID("texture"));
