WebAdd this line in your fragment shader: gl_FragColor = vec4 (texture2D (Sampler, TextureCoordOut).xyz, 0.5); You should see some half transparency texture. Ps: Your result color will be darker, because it is a mix with color in backbuffer*0.5 and the gl_FragColor*0.5. Blending is done after the fragment in the OGLES 2.0 pipeline. Your … WebA fragment is basically a position on the window (X,Y), a depth value (Z), plus all the interpolated data from previous stages. The fragments that were found in the rasterization process, and whose attributes were computed in the interpolation phase, are now fed, one by one, to the fragment shader.
