Web23 de abr. de 2013 · In desktop OpenGL, the fragment shader can output multiple colors, not just one. Each color is numbered, and each such number is mapped to an output buffer in the framebuffer, based on glDrawBuffers. Blending takes place independently between each fragment shader output color and the color currently stored in the destination image. Web19 de fev. de 2024 · You need to use dual-source blending (which means you can only be rendering to a single render target). This is a technique whereby you output two values from the FS to the same render target: layout (location = 0, index = 0) out vec4 outputColor0; layout (location = 0, index = 1) out vec4 outputColor1;

Web6. In your first example ( glBlendFunc ( GL_SRC_ALPHA, GL_ONE_MINUS_SRC_ALPHA) ), you're telling it to blend colors based on the alpha of the image which gets drawn on top (the "Foreground" one). So when you're blending 50% between the foreground color (38,50,168) and the background color (38,50,168) in the bottom left corner of the image, … Dual source blending refers to a blending mode, where the Fragment Shader outputs two colors to the same output buffer. To do this, the two outputs must both point to the same buffer index, but with a special parameter that refers to whether it is color 0 or color 1.

Web21 de out. de 2010 · The blend function can now do blending based on the two source colors and the destination color. So you can do a linear blend between src0 and dest based on src1.alpha. However, using this will cut down the number of draw buffers you can draw to. You’ll have to query MAX_DUAL_SOURCE_DRAW_BUFFERS to find out.
