WebTo attach a stencil buffer you use GL_STENCIL_ATTACHMENT as the second argument and specify the texture's formats as GL_STENCIL_INDEX . It is also possible to attach both a depth buffer and a stencil buffer as a single texture. Each 32 bit value of the texture then contains 24 bits of depth information and 8 bits of stencil information. WebBinding textures for use in OpenGL is a little weird. There are two reasons to bind a texture object to the context: to change the object (e.g. modify its storage or its parameters) or …
