Picture Shading

The picture of Ladybug Studio XP icon on the right is created in the following steps:

1. Create a bitmap picture with an available tool like Paint and save them as a JPEG file.

2. Run mCL shader diffuse-specular-shoe.mcl under the directory shaders\effects\diffuse-specular. Select your .jpg file from the Open File dialog. Your picture will be displayed on the patch. Press F1 to know the contorl keys. For example, you may use S/W key to zoom out/in the patch. Then you can use E key to move the patch left, and then use the Left Arrow key to move it back, so the patch is rendered in an angle to the window.

3. Use X/C, Y/U, and G/H key pairs to adjust light position in X, Y, or Z.

4. Snap the picture and edit it.

5. Use [$app clear ...] command in RestoreDeviceObjects() change the background color.
