Unigine::ObjectCloudLayer Class

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.
