- builtin uniforms match what Blender needs
- set input counts in struct (stupid mistake)
- look up uniforms by name
- look up builtin uniforms by enum
- check attrib/uniform locations for error
Same as MEM_SAFE_FREE macro,
checks for NULL, runs free then sets NULL.
Blocks of code that do this many times are noisy and likely
errors here wouldn't be noticed immediately.
Also NULL's static vars which were being left set.
Callers now have to use Gawain's PRIM enum to specify geometric primitives.
This makes the API more bullet-proof (at least less vulnerable) since GLenum covers waaay more than GL_POINTS, GL_LINES, etc.
Also prepares us for Vulkan.
Callers now have to use Gawain's COMP enum to specify vertex attributes.
This makes the API more bullet-proof (at least less vulnerable) since GLenum covers waaay more than component types.
Also prepares us for Vulkan.
Quads are not part of modern GL or Vulkan, so we should avoid them. XXX makes coders think "hmm how could I draw this without using quads?"
Quads will be removed during the transition to core profile.
Part of T49043
See intern/gawain for the API change. Other files are updated to use the new name. Also updated every call site to the recommended style:
unsigned int foo = VertexFormat_add_attrib(format, "foo", COMP_ ... )
This attempt at TLS was leftover from an earlier prototype. It never worked with Blender's build system, and was defined to just exist, not to actually do anything.
Before now it lived in source/blender/gpu for convenience. Only a few files in the gpu module use Gawain directly.
Tested on Mac, time to push and test on Windows.
Todo: some CMake magic to make it easy to
#include "gawain/some_header.h"
from any C or H file. Main problem here is the many editors that include GPU_immediate.h which includes Gawain's immediate.h -- is there a way to avoid changing every editor's CMakeLists?
