Hi, To start, I am grabbing the depthBuffer from the video card using the readPixel (0, 0, width, height, GL_DEPTH_COMPONENT, GL_FLOAT) method.
First, I will create a camera that will be positioned above the scene's geometry and point straight down. I'd like to take the data from the depth buffer and transfer it into memory. Next, using the data, I'd like to create a grid and translate all the depths to height above geometry. If I have an osg::Image *depth_buffer, I believe that: depth_buffer->data() takes the depthbuffer from the video card into memory. How can I store all the data into an array, iterate through it, and convert the normalized values into meaningful height values? This is an e-mail from General Dynamics Land Systems.
