R: [Plib-users] Grrr.... I only get a black screen

[Paolo L. <p.l...@ci...>]

Peter,

try these:

1. disable lighting (state->disable(GL_LIGHTING));
2. add the fourth vertex color (just three colors set for four
vertices), or just add a single color, single normal (flat shading);
3. move the sgSetCoord/setCamera to the draw() section and use rotate_
as azimuth (4th param in sgSetCoord) in order to look around.

Alternatively try loading a 3D model (get whatever 3DS model in
internet) instead of creating the leaf internally.

Let's hope and see...

Paolo
