A material global is a variable seen by all materials. There are 4 such
variable which are all vec4 and they can be set on a per-view basis.
All materials used during Renderer::render() will see the same value.
These variable can be accessed in the materials by using
getMaterialGloabal{0|1|2|3}.
- FogOption::color is now correctly multiplied by the exposure and
environment intensity.
- New option to exclude the skybox from the fog
- better documentation and naming
- -m option now works with "directory_*.png" or just "*.png"
- "color" replaced by "albedo" to mach other places in the source tree
- fixed warnings
- clear the background when IBL is not used
This change adds a 'SRGB' config flag when creating a SwapChain that
enables linear to sRGB conversion on write.
When using this flag, the linear->srgb conversion in the color grading
post processing should be disabled (or, the whole post-processing
stage should be disabled).
There is also a new query to determine if this flag is supported by
the underlaying platform.
On Metal, this happens automatically when the underlaying layer is sRGB.
This reverts commit 3799e219fc.
There can be up to 4 channels drawing commands can be associated to.
Channels work like "priorities" except it's the strongest command ordering
key, in particular it takes precedence over the object's blending mode.
In addition to the new getters, this change fixes the duplication of
a MaterialInstance, which didn't carry along the following states:
- alpha mask threshold
- specular AA threshold
- specular AA variance
- double sidedness
TODO: stencil state, polygon offset and scissor are stil not queryable
This basically adds two settings:
- highPrecision at the View level, which controls the bit depth
of the vsm shadow texture used. This affects all shadowmaps.
- elvsm per shadowmap, which enables Exponential Layered VSM.
the main change in the shaders is that we now always output the
"negative" EVSM, even when it's not enabled. If no shadowmap uses
ELVSM, then the texture is stil an RG texture and the calculation is
lost (with some luck culled by the shader compiler), either way it's
not a lot of math and it's done only once per shadow texel.
During the color pass, on the other hand, we compute the "negative"
EVSM only if enabled.
