GLGraphics. How to use multitexture with GLModel

peripecio

in Contributed Library Questions • 1 year ago

I'm interested in using the multitexture capability of GLModel to blend directly some textures over the GLModel mesh, but i don't fond how to use it.

There are some functions like

glmodel.initTextures(nTextures)

glmodel.setTexture(numTex, tex)

and

glModel.setBlendMode(xxx)

but qhen i render the GLmodel noting appears.

Thanks!

Hi again!

This is some pseudocode that serves as an example of what i want. I'm not sure that it's OK.

// load some textures

GLTexture tex1 = new GLTexture(this, "tex1.jpg");

GLTexture tex2 = new GLTexture(this, "tex2.png");

// a GLModel

calcCoordsAndVertex(); // Here we init the vertex (vertArray), colors, normals...

GLModel myModel = new GLModel(this, vertArray, TRIANGLE_STRIP, GLModel.STATIC); // static vertex

// Now declare that there are two textures associated to GLModel

myModel.initTextures(2);

myModel.setTexture(0, tex1); // one texture is with number 1

myModel.setTexture(1, tex2); // one texture is with number 2

/// render ///

// Here is the question: how could i render the model using the two textures?

myModel.setBlendMode(BLEND); // for example

myModel.render(); // does nothing: no error but no image
