Is it possible to combine 2 opengl EXTERNAL_OES texture together?

问题

I am just wondering if it is possible to combine 2 GLES11Ext.GL_TEXTURE_EXTERNAL_OES texture and access them at the same time in the fragment shader?

回答1:

1. Bind it as a GL_TEXTURE_EXTERNAL_OES texture
2. Use uniform samplerExternalOES tex0 and tex1 instead of sampler2D
