THIS CHANGE BREAKS MATERIALS.
This adds getUserTime() in shaders/materials, which returns the time
in second since Renderer::resetUserTime() was called.
Two values are provided, the time in second encoded as a float and
the difference between that and the double value, which together allows
to perform high precision time computation when needed.
This change allows longer running animations in materials. Using only
the float value, give millisecond resolution for more than 4h.
* Add View::setFrontFaceWindingInverted() API
This API can be used to flip all meshes in a render pass
inside out. This is useful for mirrored rendering.
This change also disables face culling on the default skybox
renderable. Since it is unlit, there is no downside to this
and the mesh being in the device vertex domain it can never
be backfacing unless front face winding is inverted.
* Track face winding state in Vulkan
View::setRenderQuality gives the ability to control the rendering quality
of a given view. In particular this allows the app to lower the quality
of the HDR color buffer by using R11G11B10F instead of RGB(A)16F.
This change also optimizes the size of existing images using squoosh.app.
This should make the main README a lot lighter and faster to load (it saves
several MiBs).
* WIP Add helper to upload Android bitmaps to textures
* Add missing file
* Pass custom constants for bitmap formats
* Add sample app for texturing
* Update the README for samples
* Rename variable from callback to autoBitmap
This change will allow the skybox use a compressed texture format.
For now, the old internal format "RGBM" is still honored, but in a
forthcoming change we will replace the enum with UNUSED.
* Add support for save/replay of the current view.
* Add support for having distinct draw/read surfaces.
Adds support to egl & glx drivers for distring draw/read surfaces and
uses this support to implement mirrorFrame using a single blit.
* Use src/dst, Viewport, clean up apis.
* Add SwapChain READABLE Config.
* Commit & setPresentationTime optional on mirror.
* Fix flag check.
* Add documentation for READABLE swap chain config.
* Fix missed s/ExternalContext/Platform/ cases.
* Build break fix.
* Add missing method to query the type of a light
* IcoSphere now generates front facing triangles
* Add a fairly generic sphere object to use in samples
it provides an ico sphere with normal, and reuses
the same vertex/index buffer for each new instance.
Each instance can have its own material, size and
position.
currently it’s not possible to change the # of
subdivisions.
* FilamentApp now provides a “default” pbr material
this makes it easier to create renderables for
testing.
* clean-up lightbulb and add spheres for each light
lightbulb now has less hardcoded things and it
spawns a small sphere for each light.
