This allows us to skip the CPU-side vector-to-color conversion that
occured at the end, and makes the real-time visualization consistent
with the final visualization.
This replaces the previous "curvature to roughness" method. Both are related
and rely on the screen space variance of geometric normals but this new
solution offers more control (the screen space variance and the clamping
threshold can be controlled).
* Add micro-shadowing based on ambient occlusion
* Prevent crash when IBL is turned off
* Apply micro-shadows to baked AO only
* Remove debug code
* Add opacity control
* Fix opacity term
* Switch to micro-shadowing from Chan 2018
The AO baking procedure consists of the following steps:
1. Flatten the glTF hierarchy.
2. Generate a single 2D parameterization for the entire scene.
3. Embree Pass 1: Create G-Buffer using the above UVs as vert positions.
4. Embree Pass 2: Cast rays from the positions embedded in the G-Buffer.
The `gltf_baker` tool is not ready for general use but already
produces reasonable results for certain well-formed models.
The cgltf "base path" that gets passed to cgltf_load_buffers should
actually be the path to original glTF file, otherwise bin filepaths
are resolved incorrectly.
Also use new default bias parameters that seem to work better with
more scenes.
Renamed SAMPLING_HARD to SAMPLING_PCF_HARD because the GPU still
performs 4-taps PCF.
- "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
