Hello Carsten > hm, it appears readback was only implemented for color attachments :( The > attached patch should change it to also handle depth and stencil attachments > (including combined ones). Can you give it a try and see if it works for > you, thanks! >
I applied the patch and added #define GL_DEPTH_STENCIL_EXT 0x84F9 #define GL_UNSIGNED_INT_24_8_EXT 0x84FA #define GL_DEPTH24_STENCIL8_EXT 0x88F0 #define GL_TEXTURE_STENCIL_SIZE_EXT 0x88F1 to OSGGLEXT.h Now I got some invalid enumerant calls. Here is the glTrace: ... | glEndList() | glCallList(1) | glColorMask(TRUE, TRUE, TRUE, TRUE) | glDepthFunc(GL_LEQUAL) | glDepthMask(TRUE) | glDisable(GL_LIGHTING) | glDisable(GL_COLOR_MATERIAL) | glDepthMask(FALSE) | glDepthMask(TRUE) | glMatrixMode(GL_PROJECTION) | glPopMatrix() | glMatrixMode(GL_MODELVIEW) | glPopAttrib() | glReadBuffer(GL_COLOR_ATTACHMENT0_EXT) | glReadPixels(0, 0, 64, 64, GL_RGB, GL_UNSIGNED_BYTE, 073310A8) | glReadBuffer(GL_POINTS) | glGetError() | glReadBuffer(GL_DEPTH_STENCIL_NV) W! OpenGL error GL_INVALID_ENUM detected | glReadPixels(0, 0, 64, 64, GL_UNSIGNED_INT_24_8_NV, GL_UNSIGNED_BYTE, 00000000) W! OpenGL error GL_INVALID_OPERATION detected | glReadBuffer(GL_POINTS) | glGetError() | glBindFramebufferEXT(GL_FRAMEBUFFER_EXT, 0) > glDepthMask(FALSE) I'm wondering why there is an _NV at the end of GL_DEPTH_STENCIL. Any hint or solution? Thank you very much for your help.
