问使用GL_SAMPLE_ALPHA_TO_COVERAGE并写入alpha通道ENAlpha通道技术是非曲直图像合成的最基本技术，目前其应用多局限于多媒体课件作品开发中的个别环节，未能从整体上给予Alpha通道功能以足够的重视。如：对通用图像处理软件PHOTOSHOP中的Alpha通道及其运用有较深刻的理解，而疏忽了Alpha通道在动

为此,你需要调用glEnable函数,然后传入参数 GL_SAMPLE_ALPHA_TO_COVERAGE。fragment的coverage的值将会决定有多少子样本会被写入。比如,当一个fragment的alpha值是0.4的时候,coverage的值是40%。当你使用这个方法的时候,OpenGL会先计算每个像素里的 每个样本颜色的coverage的值,然后生成一个样本的掩码。然后它会使用你...
默认情况下多重采样计算片元覆盖率不会考虑alpha,开启一下功能则会将alpha纳入参考。 .GL_SAMPLE_ALPHA_TO_COVERAGE 使用片元的alpha来聚散最后采样覆盖率,并且这个过程与硬件实现无关。 .GL_SAMPLE_ALPHA_TO_ONE 将片元的alpha值设置为最大值,然后时候这个值进行覆盖率计算。

The MotionBlur10 sample implements motion blur using a geometric approach combined with order independent transparency through the use of AlphaToCoverage and with anisotropic texture filtering. MotionBlur10 sample使用几何方法并结合顺序独立透明计算(通过使用AlphaToCoverage和各异向行纹理采样)实现运动模糊。
Alpha to Coverage, and Figure 8. Pixel Shader Ordering The sample makes no attempt to hide artifacts in the original alpha-blending solution, which in a real game could be partly solved by further subdividing the models and sorting relative to the camera. The intent is to simply show the ...
Differences in bird communities were also very robust to changes in sample coverage.The sample coverage decreased significantly along the recovery gradient and affected the different measures of alpha diversity. Although the results controlled by sample coverage showed no change in taxonomic and ...
var isAlphaToCoverageEnabled: Bool A Boolean value that indicates whether to read and use the alpha channel fragment output for color attachments to compute a sample coverage mask. var isAlphaToOneEnabled: Bool A Boolean value that indicates whether to force alpha channel values for color attachment...
