static ConvexPtr create ( ) #
Constructor. Initializes the new convex shape by clearing data of the prevoius shape.static ConvexPtr create ( const Convex& convex ) #
Constructor. Initializes the new convex shape using the given shape.Arguments
- const Convex& convex - Input convex shape.
Convex & operator= ( const Convex& convex ) #
Sets the convex shape to be equal the given convex shape.Arguments
- const Convex& convex - Convex shape.
Return value
Resulting convex shape.void clear ( ) #
Clears the data of the prevoius convex shape.bool create ( const vec3* v, int num_vertex, float error = 0.01f ) #
Creates the convex shape using the given vertices.Arguments
- const vec3* v - Vertices.
- int num_vertex - Number of vertices.
- float error - Approximation error (value in range [0..1], a higher value mean fewer vertices). This value allows reducing the number of vertices of the created shape. Convex hulls with fewer vertices are processed faster.
Return value
true if the shape was successfully created; otherwise false.bool create ( const dvec3* v, int num_vertex, float error = 0.01f ) #
Creates the convex shape using the given vertices.Arguments
- const dvec3* v - Vertices.
- int num_vertex - Number of vertices.
- float error - Approximation error (value in range [0..1], a higher value mean fewer vertices). This value allows reducing the number of vertices of the created shape. Convex hulls with fewer vertices are processed faster.
Return value
true if the shape was successfully created; otherwise false.int getNumVertex ( ) const#
Returns the number of vertices the convex shape consists of.Return value
Number of vertices.const dvec3 * getVertex ( ) const#
Returns the pointer to the array of vertices for the convex shape.Return value
Pointer to the array of vertices.const dvec3 & getVertex ( int num ) const#
Returns the vertex with the given number.Arguments
- int num - Number of the vertex.
Return value
Resulting vertex.int getNumFaces ( ) const#
Returns the number of faces for this convex shape.Return value
Number of faces.int getNumFaceVertex ( int face ) const#
Returns the number of vertices for the given face.Arguments
- int face - Number of the face.
Return value
Number of vertices.int getFaceVertex ( int face, int num ) const#
Returns the specified vertex of the specified face.Arguments
- int face - Face of the convex shape.
- int num - Number of the vertex.
Return value
Index of the vertex.double getVolume ( ) const#
Returns the convex shape's volume.Return value
Convex shape's volume.double getThreshold ( ) const#
Returns the merge threshold.Return value
Merge threshold.dvec3 getCenter ( ) const#
Returns the center of the convex shape.Return value
Center of the convex shape.mat3 getInertia ( ) const#
Returns the inertia matrix.Return value
Inertia matrix.dvec3 getClosestPoint ( const dvec3& point ) const#
Returns the closest convex shape's point to the given point.Arguments
- const dvec3& point - Given point.
Return value
Closest point (inside or on the edge of the convex shape).void getBoundBox ( dvec3& min, dvec3& max ) const#
Calculates the convex shape's bounding box (minimum and maximum vertices).Arguments
- dvec3& min - Minimum vertex of the shape.
- dvec3& max - Maximum vertex of the shape.
