I need two utility function for OpenGL: 1) Scaling I have a 2D OpenGL texture. This should be scaled to 300 pixel with (proportional). I need the result back in a CPU memory buffer as RGBA with float components. Input parameter: inputTexture Return parameter: bitmap 2) Render with lookup table I have a 2D input and output 2D texture. Also, I have a color cube in CPU memory float cube[32][32][32]; This cube should be applied o the input texture and the result rendered to the output texture. Input parameters: inputTexture, outputTexture, cube Return parameter: - Thats all. Thorsten

Hello sir, Thank you for this project. Overall I grasp the concept of your project, but when it comes o concrete implementation I have few questions: 1. For the scaling operation the width should be fixed to 300pixels and height should be adjusted based on aspect ratio ? Or maybe fix height to 300 px and adjust width ? If not, please explain. 2. The scaling operation will might need to create a new temporary texture memory. This might be inefficient depending on the application (e.g. when making many re-scale operations for real-time applications). In such scenarios I find that one possibly optimal solution would be to create just one texture upon the first call to rescale and then only reallocate memory when needed in subsequent calls if they rescaled image does not fit to the existing texture size. What is your requirements on this matter? 3. I am afraid I did not completely understand the lookup operation with the cube. Could please provide a small example on the operation that is needed ? In any case I guess this will be accomplished via a GLSL shader. Which version of OpenGL are you targeting? I would be glad to help you on this project and provide a solution that meets your needs. I am looking forward to your response. Best regards, Alex
