Hi,
I’ve made a research on previous topics but I don’t find a solution to my problem. I put this code to init my depth/stencil texture :
// Depth stencil texture initialisation
glGenTextures(1, &tmpCG->idDepthStencil);
glBindTexture(GL_TEXTURE_RECTANGLE_NV, tmpCG->idDepthStencil);
glTexParameteri(GL_TEXTURE_RECTANGLE_NV, GL_TEXTURE_MIN_FILTER, GL_LINEAR);
glTexParameteri(GL_TEXTURE_RECTANGLE_NV, GL_TEXTURE_MAG_FILTER, GL_LINEAR);
glTexParameteri(GL_TEXTURE_RECTANGLE_NV, GL_TEXTURE_WRAP_S, GL_CLAMP);
glTexParameteri(GL_TEXTURE_RECTANGLE_NV, GL_TEXTURE_WRAP_T, GL_CLAMP);
glTexImage2D(GL_TEXTURE_RECTANGLE_NV, 0, GL_DEPTH24_STENCIL8_EXT, gridInfo.resX, gridInfo.resZ, 0,
GL_DEPTH_STENCIL_EXT, GL_UNSIGNED_INT_24_8_EXT, NULL);
After this code I attach this texture to 2 FBOs :
glFramebufferTexture2DEXT(GL_FRAMEBUFFER_EXT, GL_DEPTH_ATTACHMENT_EXT, targetType, idTex, 0);
glFramebufferTexture2DEXT(GL_FRAMEBUFFER_EXT, GL_STENCIL_ATTACHMENT_EXT, targetType, idTex, 0);
I check for OpenGL error -> no problem
I check my FBOs -> COMPLETE
In my render loop I put that before drawing in my FBO using a Shader
glClear(GL_STENCIL_BUFFER_BIT);
glEnable(GL_STENCIL_TEST);
glStencilFunc(GL_ALWAYS, 1, 1);
glStencilOp(GL_REPLACE, GL_REPLACE, GL_REPLACE);
My fragment program does’nt make anything particular (just put a color in gl_FragColor for debug). So, my stencil buffer must have 1 value in every pixels but using Image Debug I see that value is 0. I don’t understand why its doesn’t work.
PS : My graphics card is a NV Quadro 3450/4000 SDI with ForceWare 91.36
