Hi, I am trying to visualize an intensity volume cube (512*512*512*float) with some modifications to osgvolume project. I plan to use shaders to test different parameters and shader code. Because it is a huge volume file (~500MB), loading time is around 40 seconds... Anyway, what I want to do is once I load this data into memory, I plan to apply different filters etc. on the data, so without compiling my application for every modification, I will change the shader codes and during the runtime I will delete the previous shader code on the GPU and load the new one. This will make my work easier because I dont need to wait 40 second each time to load the file or recompile the application.
My Question: Existing osgvolume code is: ... program->addShader(vertex_shader); ... program->addShader(vertex_shader); ... What will be the right way to update the shader code (I will not use uniforms!, because I will test different algorithms not only changing the parameters...) Is the following lines correct ? ... program->removeShader(vertex_shader); ... // update shader code... program->addShader(vertex_shader); ... program->dirty(); // or somethign like this to be called?
