This class is used to create cloud layers.

ObjectCloudLayer Class

Members

---

static ObjectCloudLayerPtr create()

Constructor. Creates a new empty cloud layer object with default properties.

static int type()

Returns the type of the object.

Return value

Object Cloud Layer type identifier.

float getIntersectionThreshold()

Returns current intersection threshold value.

Return value

Intersection threshold value.

void setAnimationNoiseOffset(const Math::vec4 & offset)

Sets a given noise animation offset value.

Arguments

• const Math::vec4 & offset - Noise animation offset (a vec4 value, where X, Y, and Z components represent 3D noise texture offsets along the X-axis, Y-axis, and Z-axis respectively).

void setAnimationCoverageOffset(const Math::vec4 & offset)

Sets a given coverage animation offset value.

Arguments

• const Math::vec4 & offset - Coverage animation offset (a vec4 value, where X and Y components represent coverage texture offsets along the X-axis and Y-axis respectively).

Math::vec4 getAnimationNoiseOffset()

Returns current noise animation offset value.

Return value

Noise animation offset (a vec4 value, where X, Y, and Z components represent 3D noise texture offsets along the X-axis, Y-axis, and Z-axis respectively).

static Ptr<ObjectCloudLayer> cast(const Ptr<Node> & node)

Casts an ObjectCloudLayer out of the Node instance.

Arguments

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

Return value

Pointer to ObjectCloudLayer.

float getIntersectionAccuracy()

Returns current intersection accuracy value.

Return value

Intersection accuracy value.

int getWorldIntersection(const Math::Vec3 & wp0, const Math::Vec3 & wp1, Math::vec3 * ret_point, Math::vec3 * ret_normal, Math::vec4 * ret_texcoord)

Searches for intersections with a given line.

Arguments

• const Math::Vec3 & wp0 - Line start point coordinates in the world space.
• const Math::Vec3 & wp1 - Line end point coordinates in the world space.
• Math::vec3 * ret_point - Intersection point coordinates.
• Math::vec3 * ret_normal - Normal vector of the intersection point.
• Math::vec4 * ret_texcoord - Texture coordinates of the intersection point (vec4, where X and Y components are used for the first (0) UV channel, and Z and W components - for the second (1) UV channel).

Return value

1 if intersections are found; otherwise, 0.

void setIntersectionAccuracy(float accuracy)

Sets a given intersection accuracy value.

Arguments

• float accuracy - Intersection accuracy value.

void setIntersectionThreshold(float threshold)

Sets a given intersection threshold value.

Arguments

• float threshold - Intersection threshold value.

Math::vec4 getAnimationCoverageOffset()

Returns current coverage animation offset value.

Return value

Coverage animation offset (a vec4 value, where X and Y components represent coverage texture offsets along the X-axis and Y-axis respectively, both Z and W components are 0).

static Ptr<ObjectCloudLayer> cast(const Ptr<Object> & base)

Casts an ObjectCloudLayer out of the Object instance.

Arguments

• const Ptr<Object> & base - Pointer to Object.

Return value

Pointer to ObjectCloudLayer.
