StereoPaint Tutorial
We will convert the startup.jpg image found in the ./workarea folder.
Step 1.
Cross your eyes as for normal cross-eye stereo viewing so that you can see the
cursor floating above the image.
(Focus on left image with your right eye, right image with your left eye. For
cross-eye training click here )
Step 2.
Let's do the ground first.
Activate Gradient Floor Mode by pressing '4' above the qwerty keys.
Move the cursor up and down, notice how it goes in and out depending on the
y position
The cursor is too high, use the mouse wheel to adjust the depth until it looks
like it would run along a floor in 3D.
Press the middle button to 'pick up' depth from the depthmap image. In this
case the cursor snaps to 0 depth.
The angle is slightly wrong, press A and S to adjust it ( values nearer 0 mean
more angle, e.g. 10-20 are typical floor angles. )
You can see the current angle value on the toolbar, along with other useful
information.
Click and drag on the floor in the right image to paint the depth.
Notice how the depth map changes to show the depth you are painting, in Floor
mode the colour on the depth map is lighter at the bottom and darker at the
top.
Step3.
When you have finished the floor press '2' to activate round brush mode. This
is a good mode for fine detail around organic corners like arms and trees.
Press Shift and use the mouse wheel to adjust the cursor size.
Press the middle button to pick up depth from the depthmap.
e.g. if you want to continue with a tree in the middle distance pick up depth
of the ground next to the tree and use it to complete the tree's depth, using
the mouse wheel to make subtle depth adjustments.
Continue with the image, using flat and gradient modes to generate depth.
Eexperiment with the different modes.
It should be possible to convert the sample image to 3D in a few minutes.
Save the composite image and then save the depth map.

Lighter areas are nearer the viewer, darker areas further.
