Regretfully, I'll no longer be able to provide feedback about
what's seen when using a Ti4200. I just upgraded the graphics card
to a PNY FX5700LE. I just couldn't stand not being able to see the
multiple eclipse shadows!
Not too surprisingly, the low priority bugs I saw when using the 4200
also are present when using the 5700:
> 1) With the planet's surface texture commented out for my PlanetCastor,
> when using either "Render path: OpenGL vertex program"
> or "Render path: OpenGL vertex program/Nvidia combiners"
> the entire hemisphere goes black as soon as the moon's shadow
> touches the surface. It should only darken a portion of the surface.
> If the surface texture is not commented out, then the proper
> oval shadow is cast.
> 2) With the planet's surface texture ommented out,
> neither "Render path: Basic" nor "Render path: Multitexture"
> generate any eclipse shadow.
> 3) With the planet's surface texture *not* ommented out,
> "Render path: Basic" projects the shadow of the moon through
> the planet onto the side away from the illuminating star.
> (With the planet's surface texture *not* ommented out,
> the higher Render paths correctly draw the shadow only on the
> side of the planet illuminated by the star casting the shadow.
> (Only one of the two stars, the white one, is casting
> any shadow. No eclipse shadow is cast by the red star.)
