3D Texturing Example (with LGL)

3D Texture Example | | 3D Texture Interpolation Nearest Neigbour

3D texture is supposed to be given as texture object with id texid.

// bind specific texture
lglTexture3D(texid);

// transfrom texture into world coordinates
lglMatrixMode(LGL_TEXTURE);
lglLoadIdentity();
lglTranslate(0.5,0.5,0.5);
lglMatrixMode(LGL_MODELVIEW);

// render textured geometry
lglColor(1,1,1);
lglBegin(LGL_QUADS);
   lglTexCoord(x_0,y_0,z_0);
   lglVertex(x_0,y_0,z_0);
   lglTexCoord(x_1,y_1,z_1);
   lglVertex(x_1,y_1,z_1);
   lglTexCoord(x_2,y_2,z_2);
   lglVertex(x_2,y_2,z_2);
   lglTexCoord(x_3,y_3,z_3);
   lglVertex(x_3,y_3,z_3);
lglEnd();

// unbind texture
lglTexture3D(0);
