API transition guide not accessible #4

Closed BearishSun closed 4 years ago

BearishSun commented 4 years ago

Release notes reference the following link: https://github.com/Radeon-Pro/RadeonProRenderSDK/wiki/1.34.9-1.35.0-transition-for-RPR-developers

But it cannot be accessed (Nor can the Wiki page be opened at all).

This link is an old repo that we have closed now.

The main change was about env light override.

remove of : rprSceneSetEnvironmentOverride rprSceneGetEnvironmentOverride rprEnvironmentLightSetEnvironmentOverride rprEnvironmentLightGetEnvironmentOverride

replaced by :
rprEnvironmentLightSetEnvironmentLightOverride rprEnvironmentLightGetEnvironmentLightOverride

You can override different types of lights :
RPR_ENVIRONMENT_LIGHT_OVERRIDE_REFLECTION RPR_ENVIRONMENT_LIGHT_OVERRIDE_REFRACTION RPR_ENVIRONMENT_LIGHT_OVERRIDE_TRANSPARENCY RPR_ENVIRONMENT_LIGHT_OVERRIDE_BACKGROUND

Example: 

rprSceneAttachLight(scene, envLightA);
rprEnvironmentLightSetEnvironmentLightOverride(envLightA, RPR_ENVIRONMENT_LIGHT_OVERRIDE_REFLECTION, envLightB);

Means the scene is going to use envLightA for the lighting. Except for the "reflection" lighting : envLightB will be used.

I think that was the only difference between 34.9 and 35.0. But if you have other questions about this transition, feel free to ask.
