ptwaixingren created an issue

Hi everyone, I want to use Coin3D draw the shadow of a cube, I create a light node and add the node before the cube node.I used the SoShadowGroup too, but there was't shadow. I also install the newest Nvidia driver to insure the opengl version > 2.0. Can anyone tell me how can I draw the shadow?

    Can you append a copy of your scenegraph (.iv or .wrl file). If you are creating it directly in code you could use a SoWriteAction to output the scene to a file.

    Hi ptwaixingren,

    The example code in the SoShadowGroup class reference should produce shadows on the floor (something similar to this scene / result). If it doesn't then your graphics card might indeed be unsupported. The example works fine for me on NVIDIA and Intel chips.

    Thank you TheHubbit, I test as the scene file you told me. and produce shadows on the floor
