cegui renderer base on ogre 1.10.x material

Post by longer » Tue Jun 19, 2018 9:17 am

Hi everyone. I write a cegui renderer base on ogre 1.10.x material, different from the official original shader version.
I think a material script for cegui is batter than fixed in the source code.

I have not cmake build system here.
The dependence environment is consistent with the cegui official CEGUIOgreRenderer.
The project now is just part of my other subdirectory.https://bitbucket.org/mm_longcheng/mm_core

Code: Select all

   code     at mm_core\flake\src\CEGUIOgreRenderer
   material at mm_core\flake\resources\assets\cegui\materials
I think it's eazy build it by just copy code to official CEGUIOgreRenderer, or create new project.

Main change:
1.Add setDefaultMaterial api for CEGUIOgreRenderer.
2.Copy the Ogre::SceneManager _setPass process into CEGUIOgreRenderer.
3.CEGUIOgreGeometryBuffer change.

Code: Select all

   a.texture_alias name CEGUIOgreGeometryBuffer::AliasTextureName("CEGUI/GeometryBuffer")
   b.CEGUIOgreGeometryBuffer public Ogre::Renderable
4.Improve resource loader for CEGUIOgreTexture.

The shader is copy from official original shader, change the worldViewProj name:
CEGUI_GeometryBufferVP_*
CEGUI_GeometryBufferFP_*

The material CEGUI/GeometryBuffer is use for base cegui GeometryBuffer.
The material CEGUI/TextureTarget is use for cegui rtt to ogre.

Texture alias

Code: Select all

cegui renderer set_texture_alias CEGUIOgreGeometryBuffer::AliasTextureName("CEGUI/GeometryBuffer") texture->getTextureNameAlias()
cegui renderer set_texture_alias CEGUIOgreTextureTarget::AliasTextureName("CEGUI/TextureTarget") texture->getTextureNameAlias()
The material:
CEGUI_Layout.material
