mat4 getBasis ()

Returns the current basis of the coordinate system for the handler. It can either be the world coordinates (identity matrix, by default) or coordinates of the parent node if the manipulated node is a child.

Return value

Matrix, which columns specify basis vectors.

vec4 getColor ()

Returns the current color for a manipulator. The default is vec4(1).

Return value

Manipulator color.

int getMask ()

Returns a mask that hides axis arrows (along X, Y or Z) of the handler.

Return value

3-bit mask for axes.

mat4 getModelview ()

Returns the current projection matrix of the handler.

Return value

Model-view matrix.

mat4 getProjection ()

Returns the current model-view matrix of the handler.

Return value

Projection matrix.

int getSize ()

Returns the current handle size of the manipulator. Depending on the handle shape, this can be a radius or an altitude. The default is 128 pixels.

Return value

Size in pixels.

float getStep ()

Returns a step, which is used to align objects.

Return value

Step in units.

mat4 getTransform ()

Returns the current transformation matrix of the handler.

Return value

Transformation matrix.

void setBasis (mat4 matrix)

Sets a basis of the coordinate system for the handler. It can either be the world coordinates (identity matrix, by default) or coordinates of the parent node if the manipulated node is a child.

Arguments

• mat4 matrix - Matrix, which columns specify basis vectors.

void setColor (vec4 color)

Sets the color for a manipulator. The default is vec4(1).

Arguments

• vec4 color - Manipulator color. The provided value is clamped to a range [0;1].

void setMask (int mask)

Hides axis arrows (along X, Y or Z) of the handler.

Arguments

• int mask - 3-bit mask for axes.

void setModelview (mat4 matrix)

Sets a model-view matrix for the handler.

Arguments

• mat4 matrix - Model-view matrix.

void setProjection (mat4 matrix)

Sets a projection matrix for the handler.

Arguments

• mat4 matrix - Projection matrix.

void setSize (int size)

Sets a handle size of the manipulator. Depending on the handle shape, this can be a radius or an altitude.

Arguments

• int size - Size in pixels.

void setStep (float step)

Sets a step, which is used to align objects.

Arguments

• float step - Step in units.

void setTransform (mat4 matrix)

Sets a transformation matrix for the handler.

Arguments

• mat4 matrix - Transformation matrix.
