We tell WebGL we want to affect unit 0. We then call bindTexture () which binds the texture to the TEXTURE_2D bind point of texture unit 0. We then tell the shader that for the uSampler use texture unit 0.

WebApr 9, 2024 · Now both textures are distinguished via last attrib pointer, one float 0.0f for first texture, 1.0f for second one (and are converted to int to be used as index inside shader). But in the output, only the first one, namely the logo.png (as it is set first via Bind2DTexture (0, logo_id); will be drawn, whereas chessboard.png will not. WebJun 11, 2013 · The texture coordinate is the normalized coordinate of the texel you want to fetch.
