| Summary | 0030374: Visualization, TKOpenGl - activate texture unit Graphic3d_TextureUnit_1 after OpenGl_LayerList::renderTransparent() | ||||
| Description | OpenGl_LayerList::renderTransparent() uses 2 texture units when OIT enabled, which are unbound in the following way:
theOitAccumFbo->ColorTexture (1)->Unbind (aCtx, Graphic3d_TextureUnit_1);
theOitAccumFbo->ColorTexture (0)->Unbind (aCtx, Graphic3d_TextureUnit_0);
This code is OK within OCCT itself, but combination with external OpenGL renderer (e.g. Qt) might produce unexpected results due to this renderer not switching texture unit to 0 before usage. | ||||
