- "stable" mode disables all resolution optimizations that can affect
stability of the shadow map (e.g. lispsm, focusing)
- expose near/far hint + stable option to java
This is our first ImGui extension, it draws a draggable 3D arrow for
manipulating a unit vector. This is especially useful for tweaking the
light direction.
* Add postLightingColor property to materials
This property can be used to modify the color computed in the lighting
passes of the materials. That color is blended with the computed color
according to the postLightingBlending option (add, transparent or opaque).
* Remove test
* Update docs
* Address code review comment
* Switch postLightingColor default blend mode to transparent
* Removed STL headers from filameshio/MeshReader.h modified the samples to work the same, and made an effort to remedy the jsbindings although I'm not experienced with them.
* Fixed assignment operators for MaterialRegistry
* Fixed formating for MeshReader Material Registry
* Forgot one format
* Forgot another format
In this first step, we just "blindly" move everything under src/driver
to a new library libbackend.a. And all headers are moved under
private/backend.
Note that "driver" is renamed "backend", but namespaces are unchanged for now.
Later we'll have to untangle the actual private headers from public
ones and ideally not have any private headers.
It's now possible to enable/disable tone-mapping, fxaa, msaa and
dynamic resolution independently.
A new set/getToneMapping() method is added to View.
It's still possible to disable *all* these post-processing effects
together using setPostProcessing(). This is currently needed when
rendering a transparent view (such as UI) on top of another view.
This limitation might be addressed in the future.
This fixes#621
The new gltf_viewer app has an optional zero-arguments mode whereby it
loads a resgen-embedded binary model, which is useful for quick
sanity testing. If you don't specify an IBL, it loads a compressed
version of the pillars IBL.
This is effectively moving all shader computations to view space,
improving floating-point precision in the shaders, by staying
around zero where fp precision is highest. This also ensures that
when the camera is very far from the origin, objects are still
rendered and lit properly.
Assimp's CalcTangentSpace deviates from de facto glTF 2.0 so we were
compensating for this with an unconditional fixup in MeshAssimp. However
the fixup should apply only when CalcTangentSpace is active, i.e. when
the model is missing tangents.
This makes it so that NormalTangentMirrorTest (has tangents) and
NormalTangentTest (needs tangents) both look reasonable.
I also noticed that MeshAssimp was inexplicably applying
aiProcess_CalcTangentSpace twice: once as a flag, and once as a
post-process. I removed the latter.
This will be fixed in the upcoming cgltf-based loader, which will
use our officially-sanctioned utility method in VertexBuffer.
See #528
This class will not extend well to glTF so this cordons it off into the
filamesh namespace, which is an already-existing namespace that we use
for the things related to the filamesh file format.
For glTF we might create a new library with its own MeshReader so
this will mitigate confusion.
- baseColorFactor.a was not taken into account
- Some glTF files do not set `doubleSided` properly, so here we assume
that non-opaque materials are double-sided. We may need to revisit
this decision later...
* Add specular anti-aliasing properties to materials
curvatureToRoughness
limitOverInterpolation
These techiques were supposed to be enabled by default on
desktop but it turns out they were broken. They must now
be enabled manually on each material instead (and work on
mobile).
* Update docs/Materials.md.html
This is similar to its WebGL and Android counterparts, we simply did not
have a version for desktop. This uses resgen to package the model's
textures (albedo, normal, roughness, metallic, ao) into a library that
is linked only to this sample.
This is a good test because it applies multiple textures to the model.
Moreover Aaron was asking me for a C++ example that uses compressed
textures.
For now this selects the OpenGL backend. We can change it to use Vulkan
after we add support for 3-band formats to VulkanDriver.
* Turn on shaders optimization by default
Release builds of Filament only work well with optimize shaders,
turning optimizations on by default will help avoid mismatches.
This change also adds -g to disable all optimizations, for debug
builds.
* Use -g on debug builds
* Use -g on debug builds
* Update tutorial_redball.md to remove matc's -O
* Update tutorial_suzanne.md to remove matc's -O
* Use -g in debug builds
* grouped MeshAssimp arguments into struct
* added snormuv optimization to MeshAssimp and changed snormuv optimization range from [0, 1] to [-1, 1] in filamesh
