Web10 de jan. de 2024 · You can remap the OpenGL range to the Vulkan range fairly easily with: gl_Position.z = (gl_Position.z + gl_Position.w) / 2.0; The other option is to modify the perspective matrix to match up with Vulkan. WebglPushMatrix pushes a copy of the current matrix onto the current stack, while glPopMatrix pops the top of the stack (changing the current matrix to whatever was just below the top). Note: the stack depth limited (though at least 32 for GL_MODELVIEW and at least 2 for the other modes including GL_PROJECTION ), so be careful how many things you push.
