C++ Project of Panda3D Render Pipeline (Python)

Render Pipeline C++

This project is C++ ported version of Render Pipeline.

And I am developing the project and new features for CR Software Framework (...).

Build Status

Build Status	About
	Visual Studio 2017

Library Requirements

• Panda3D
• Boost

Optional Third-party

These are required when you include related headers to access internal data.

• yaml-cpp: required when to access YAML node.
• spdlog: required when to access the internal logger of spdlog.
• assimp: required to use rpassimp plugin.

Tested Platforms

I tested it in the following platforms:

• Intel CPU, NVIDIA GPU, Windows 10 64-bit, Visual Studio 2017
• Intel CPU, Intel GPU (UHD Graphics 620), Windows 10 64-bit, Visual Studio 2017

render_pipeline_cpp's Issues

Documents and Image

• How to control Day Time
• How to implement stereo plugin
• How to strip debugging symbol in PDB
• How to use third-party in plugin
• Caution when using Messenger
  • Messenger is NOT thread-safe.
  • Sending event with queuing is thread-safe.

Implement ShowBase::windowEvent

ShowBase::windowEvent is not implemented yet.

Some 2D window positions have bugs.

Crash when exiting OpenVR project

Problem

After v0.4.0, OpenVR projects are crashed when exiting.

Reason

OpenVR plugin creates new MatrixLens which is used for VR lens.
However, when exiting, the lens is not removed even after unloading plugin.

Change include order of flatbuffer after updating flatbuffer

https://github.com/bluekyu/render_pipeline_cpp/blob/master/src/rpcore/util/rpmodel.cpp#L22

Incorrect size of rppanda::DirectButton

In Music-box example, the size of 'open' button is different with original example.

Add iterator decorator for NodePath

Add missing functions to Messenger

• isAccepting
• ...

Resolve canonical path bug with junction point in Boost::fs

boost::filesystem::canonical() generates wrong path when the path has junction point. This is boost::fs bug.

See:

• https://svn.boost.org/trac10/ticket/10900
• https://svn.boost.org/trac10/ticket/11138

Use rplight in panda3d/contrib

See panda3d/panda3d#223 and tobspr/RenderPipeline#89

And it requires copying headers and adding dll target to use p3drplight.dll

Global cache is not used in Effect

Update spdlog to 0.14.0

Add square point effect to PointsNode

Implement DirectEntry

Fix cases in FindFlatBuffers.cmake

To improve compatibility in Linux

Add unlit material

This material should show original textures and be not shadowed.

No lighting

return vec3(0) in shade_material_from_tile_buffer() in lighting_pipeline.inc.glsl

No shadow

PSSM

result = 1; return; in main() in filter_pssm_shadows.frag.glsl

Sun shadow

result = scene_color; return; in main() in apply_sun_shading.frag.glsl

Ambient

Solution

1. Do glValidateProgram after GL states is ready.
   • However, glValidateProgram cause performance degradation while rendering.
2. Use layout(binding)
