save greater-than-one float in texture!!solved!!!!

[shapeare]

I saved some values in a matrix, and want to use the matrix to initialize a texture.

Some of the values in the matrix are greater than one, and they are all in floating format.

The texture is generated using the following code:


glTexImage2D(GL_TEXTURE_2D, 0, GL_RGBA, imageWidth,
imageHeight, 0, GL_RGBA, GL_FLOAT, myMatrix);


However, when I use gDEBugger to check the value saved in the texture, only to find that all values are less than one. Why? How to solve this problem?

Try RGBA32F as internal format (or RGBA32F_ARB)

Thank you very much. It is correct now.
