Elias Naur	61529c2cb6	gpu: fix clip intersection with the D3D backend ... Signed-off-by: Elias Naur <mail@eliasnaur.com>	2020-03-11 16:23:35 +01:00
Elias Naur	c34c350a52	gpu: pack 2D transforms in vec4 values ... Instead of separate 2d scale and transform, pack them into a single 4d value. Signed-off-by: Elias Naur <mail@eliasnaur.com>	2020-02-27 21:22:59 +01:00
Elias Naur	646a767665	gpu,gpu/gl: implement shader uniform buffers ... Emulate them for the OpenGL ES backend because 2.0 doesn't support uniform buffers. The future d3d backend only supports uniform (constant) buffers. Signed-off-by: Elias Naur <mail@eliasnaur.com>	2020-02-27 20:34:22 +01:00
Elias Naur	ac7029fa24	gpu/internal/shaders: generate shader variants ... We're about to add Direct3D support, where shaders are written in HLSL. Rather than write shaders twice (or more), convert them to a GLSL variant understood by the glslcc cross-compiler and generate the OpenGL ES 2.0 and HLSL variants. The HLSL is used by a future change. Signed-off-by: Elias Naur <mail@eliasnaur.com>	2020-02-27 20:34:22 +01:00
