The following article discusses Vertex Texture Fetch feature of todays GPUs. Vertex Texture Fetch will be referred to as VTF from now on. Texture image units will be referred to as TIU. VS means vertex shader FS means fragment shader What version of GL supports VTF? In order to be able to do VTF, you need shader support.

Hi, Thank you for contacting Microsoft Community. I appreciate your time and effort. Shader model versions are built into your video card. If your video card doesn't support shader model 3.0 the only way to get it is to buy a new video card.

I have actually used the histogram calculation from an opensource project and have absolutely no idea how the thing works.anyway i am getting the histogram when i am using glreadpixel and passing on the pixel data to the shader as attribute and triggered using GLES30.glDrawArrays(GLES30.GL_POINT, 0, #no of pixel); now i wanted to do texture reads in vertex shader to avoid glreadpixel ,in that ...

Shader Model 2.0 is such a vague term. Each vendor had their own variation on Shader Model 2.0 and the differences really were not resolved until Shader Model 3.0 was standardized; thus you had SM2a, SM2b and SM2c. Vertex texture fetches are actually a Shader Model 3.0 feature.
https://en.wikipedia.org/wiki/High_Level_Shader_Language
The High-Level Shader Language or High-Level Shading Language (HLSL) is a proprietary shading language developed by Microsoft for the Direct3D 9 API to augment the shader assembly language, and went on to become the required shading language for the unified shader model of Direct3D 10 and higher.. HLSL is analogous to the GLSL shading language used with the OpenGL standard.

Mar 17, 2019 · Checking for GL_NV_vertex_program2 solved this problem. Also Checking for GL_NV_vertex_program3 is usefull to detect vertex texture fetch. Unfortunately requiring GL_NV_vertex_program extension raises another problem: ATI cards do not report this extension. So the final question is: How to detect if Shader Model 2.0 and 3.0 is supported on ATI ...
