[SOLVED] Default Shader in SOFA

[sayakbiswas]

Hi,

I’m trying to write a custom shader for my scene. I know that I need to include OglShader tag in the .scn file. However, I was curious to understand what happens when there is no OglShader tag. I was unable to file any default shader in /share/shaders or in the code. Any pointers would be appreciated.

Thanks,
Sayak

Hello,

I guess you are speaking about “OglShader tag” to mean “ ” (that is to say, a node in the XML tree and not a tag)

If so, if there is no OglShader node in your file, then the rendering will use standard OpenGL fixed pipeline methods.
Mode doc about Shader :

Shaders

You can see a simple use of shader into Sofa by having a look at the different examples located in examples/Components/visualmodel (OglShader.scn, OglShader_tessalation.scn)

Hi Froy,

Thanks for the information. I was successfully able to implement a PN_QUADS tessellation shader for our scene.

Thanks,
Sayak
