omni::avreality::rain::PuddleBaker

Defined in omni/avreality/rain/PuddleBaker.h

Functions

class PuddleBaker

Bake puddles into dynamic textures.

Public Functions

PuddleBaker() = delete

Creates a new PuddleBaker.

Public Static Functions

static inline void bake(std::string textureName, carb::Uint2 textureDims, carb::Float2 regionMin, carb::Float2 regionMax, gsl::span<const carb::Float2> puddlesPositions, gsl::span<const float> puddlesRadii, gsl::span<const float> puddlesDepths)

Bake puddles to the dynamic texture textureName

Warning

The size of puddlesPositions, puddlesRadii and puddlesDepths must be the same.

Parameters

  • textureName – The name of the dynamic texture to bake into.

  • textureDims – The dimensions of the generated texture.

  • regionMin – The 2D world space minimum of the region the texture maps onto.

  • regionMax – The 2D world space maximum of the region the texture maps onto.

  • puddlesPositions – A pointer to the 2D positions of the puddles.

  • puddlesRadii – A pointer to the radii of the puddles.

  • puddlesDepths – A pointer to the depths of the puddles.

static inline void bake(std::string textureName, carb::Float2 regionMin, carb::Float2 regionMax, gsl::span<carb::Float2> puddlesPositions, gsl::span<float> puddlesRadii, gsl::span<float> puddlesDepths)

Bake puddles to the dynamic texture textureName

Note

Generated texture size defaults to 1024x1024.

Warning

The size of puddlesPositions, puddlesRadii and puddlesDepths must be the same.

Parameters

  • textureName – The name of the dynamic texture to bake into.

  • regionMin – The 2D world space minimum of the region the texture maps onto.

  • regionMax – The 2D world space maximum of the region the texture maps onto.

  • puddlesPositions – A pointer to the 2D positions of the puddles.

  • puddlesRadii – A pointer to the radii of the puddles.

  • puddlesDepths – A pointer to the depths of the puddles.

static inline void assignShadersAccumulationMapTextureNames(gsl::span<std::tuple<const pxr::SdfPath, const std::string>> shaderPathsAndTextureNames, omni::usd::UsdContext *usdContext = nullptr)

Assign dynamic textures to the water accumulation entry in the provided shader list.

Parameters

  • usdContext – The Usd context holding the prims to update.

  • shaderPathsAndTextureNames – The shaders to assign the dynamic textures to, provided as a list of tuple of shader path and associated texture name.
