Fixed using GL_SAMPLE_ALPHA_TO_COVERAGE A few things were failing when trying to use GL_SAMPLE_ALPHA_TO_COVERAGE: - The alpha test should not be skipped when GL_SAMPLE_ALPHA_TO_COVERAGE is set, otherwise no computation is performed. - The alpha reference value was wrong (the alpha-to-coverage ramp is centered around it) Change-Id: Ib9849868d267ca49fb3f0112192af8f207d34307 Reviewed-on: https://swiftshader-review.googlesource.com/8308 Reviewed-by: Alexis Hétu <sugoi@google.com> Reviewed-by: Nicolas Capens <capn@google.com> Tested-by: Alexis Hétu <sugoi@google.com>
SwiftShader is a high-performance CPU-based implementation of the OpenGL ES and Direct3D 9 graphics APIs12. Its goal is to provide hardware independence for advanced 3D graphics.
The SwiftShader libraries act as drop-in replacements for graphics drivers.
On Windows, most applications can be made to use SwiftShader's DLLs by placing them in the same folder as the executable. On Linux, the LD_LIBRARY_PATH environment variable or -rpath linker option can be used to direct applications to search for shared libraries in the indicated directory first.
Prebuilt binaries can be found at: https://goo.gl/5MOcdb
