hlslPatchGregoryBasis.hlsl is an equivalent to glslPatchGregoryBasis.
Update dxViewer to be able to switch among bspline, gregorybasis, legacy
end capping.
also fixes a bug of GLSL legacy gregory shader which had an inconsistent
resource naming with example codes.
It looks like there's still an issue of D3D11 patchParam data fetching.
we'll come back to that bug.
While this may be worth revisiting, we should first quantify the benefits and
identify the compilers that support it. Ultimately, we may never use pragma
once in favor of strictly using standard C++.
The code in farViewer that was used to draw the Hbr representation
of meshes is now gone. This code was mostly used as a way to compare
against the Vtr implementation. However, we don't want this to serve
as an example for others as the Hbr code is not meant to be instructive
otherwise.
- added new class to far/topologyLevel.h
- updated TopologyRefiner to manage set of TopologyLevels internally
- added TopologyRefiner method to retrieve TopologyLevel
- redefined obsolete TopologyRefiner methods in terms of TopologyLevel
The most up-to-date version of the HLSL compiler is now shipped as part
of the Windows SDK. Previously, the HLSL compiler was included with
the DirectX SDK.
There is more that we can do to improve this cmake module, but this
makes it more likely to find the correct tool.
As a preparation for retiring DrawContext, move SupportsAdaptiveTessellation
method to examples/common/glUtils, which is renamed and namespaced
from gl_common.{cpp,h} to be consistent to other files.
Same renamings applied to other example files.
This examples is rewritten as a more comprehensive example
of Far and Osd APIs to generate batched index buffer and
vertex buffer, as well as sharing same topology and stencil
table among multiple objects.
Also this change includes an experimental code path of using
glMultiDrawElementsIndirect. It's currently incomplete due to
the missing interface of osd tessellation shader.
This restores the previous defaults and works around an
apparent runtime error on some platforms which is triggered
in the legacy gregory patch drawing code when patch culling
is disabled.
Remove DrawRegistry from osd layer and put a simple shader caching
utility into examples/common. osd layer only provides patch shader
snippet and let client configure and compile the code. Clients also
maintain the lifetime of shader object, which is preferable for the
actual application integration.
update all examples to use the new scheme.
These are now redundant since all bspline patches are encoded in
the patch tables consistently using 16 point indices with boundary
and corner edges indicated in the boundary mask of the patch params.
