Casts a LightEnvironmentProbe out of the Node instance.

Arguments

  • const Ptr<Node> & node - Pointer to Node.

Return value

Pointer to LightEnvironmentProbe.

Ptr<LightEnvironmentProbe> cast(const Ptr<Light> & base)

Casts a LightEnvironmentProbe out of the Light instance.

Return value

Ambient intensity value.

void setAttenuationDistance(const Math::vec3 & distance)

Sets the distance from the light source shape, at which the light source doesn't illuminate anything.

Arguments

  • const Math::vec3 & distance - Distance from the light source shape, at which the light source doesn't illuminate anything.

Math::vec3 getAttenuationDistance()

Returns the distance from the light source shape, at which the light source doesn't illuminate anything.

Return value

Distance from the light source shape, at which the light source doesn't illuminate anything.

void setBoxGI(int boxgi)

Arguments

  • int boxgi

int isBoxGI()

void setBoxGlossCorners(float corners)

Arguments

  • float corners

float getBoxGlossCorners()

void setBoxProjection(int projection)

Arguments

  • int projection

int isBoxProjection()

void setBoxSize(const Math::vec3 & size)

Arguments

  • const Math::vec3 & size

Math::vec3 getBoxSize()

void setDynamic(int dynamic)

Sets the value indicating if reflections are dynamic (the cubemap is generated dynamically).

Arguments

  • int dynamic - 1 to enable dynamic reflections; 0 to use a reflection cubemap.

int isDynamic()

Returns the value indicating if reflections are dynamic (the cubemap is generated dynamically).

Return value

1 if dynamic reflections are used; 0 if a reflection cubemap is used.

void setImageTexture(const Ptr<Texture> & texture)

Arguments

  • const Ptr<Texture> & texture

Ptr<Texture> getImageTexture()

int setImageTextureImage(const Ptr<Image> & image, int dynamic = 0)

Sets the given image as the cube texture of the environment probe. If you need to set the cube texture for all environment probes in the scene, set the dynamic flag to 1.

Arguments

  • const Ptr<Image> & image - Cube texture to set.
  • int dynamic - Dynamic texture flag:
    • If set to 0, changing the cube texture of the current environment probe will also affect all environment probes in the scene.
    • If set to 1, a cube texture will be successfully set only for the current environment probe.

Return value

1 if the cube texture is set successfully; otherwise, 0.

int getImageTextureImage(const Ptr<Image> & image)

Grabs the cube texture (RGBA16F) containing the rendered environment probe and saves it into the given Image instance.

Arguments

  • const Ptr<Image> & image - Image into which the texture is saved.

Return value

1 if the cube texture has been grabbed successfully; otherwise, 0.

void setImageTextureName(const char * name)

Sets a path to a cube texture.

Arguments

  • const char * name - Path to a cube texture.

const char * getImageTextureName()

Returns the path to the reflection cube texture used for the environment probe.

Return value

Path to the cube texture.

void setLocalSpace(int space)

Arguments

  • int space

int isLocalSpace()

void setReflectionColor(const Math::vec4 & color)

Sets given reflection color to the LightEnvironment Probe. If reflection intensity is set to 1 and ambient intensity is set to 0, the Probe will be pure Reflection Probe.

Arguments

  • const Math::vec4 & color - Color value.

Math::vec4 getReflectionColor()

Returns a reflection color of the LightEnvironment Probe.

Return value

Color value.

void setReflectionIntensity(float intensity)

Returns the mask that specifies materials to reflect.
Notice
The reflection mask can be specified only for dynamic reflections (when the Dynamicflag is set to1).
