WidgetManipulator (Gui gui)

Arguments

• Gui gui

float getStep ()

Returns a step, which is used to align objects.

Return value

Step in units.

void setTransform (Mat4 transform)

Sets a transformation matrix for the handler.

Arguments

• Mat4 transform - Transformation 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 setModelview (Mat4 modelview)

Sets a model-view matrix for the handler.

Arguments

• Mat4 modelview - Model-view matrix.

vec4 getColor ()

Returns the current color for a manipulator.

Return value

Manipulator color.

Mat4 getTransform ()

Returns the current transformation matrix of the handler.

Return value

Transformation matrix.

void setColor (vec4 color)

Sets the color for a manipulator.

Arguments

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

Mat4 getBasis ()

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

Return value

Matrix, which columns specify basis vectors.

int getSize ()

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

Return value

Size in pixels.

mat4 getProjection ()

Returns the current model-view matrix of the handler.

Return value

Projection matrix.

void setMask (int mask)

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

Arguments

• int mask - 3-bit mask for axes.

void setStep (float step)

Sets a step, which is used to align objects.

Arguments

• float step - Step in units.

void setProjection (mat4 projection)

Sets a projection matrix for the handler.

Arguments

• mat4 projection - Projection matrix.

Mat4 getModelview ()

Returns the current projection matrix of the handler.

Return value

Model-view matrix.

int getMask ()

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

Return value

3-bit mask for axes.

void setBasis (Mat4 basis)

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

Arguments

• Mat4 basis - Matrix, which columns specify basis vectors.

int type ()

Return value

WidgetManipulator getWidgetManipulator ()

Return value

WidgetManipulator create (Widget widget)

Arguments

• Widget widget

Return value
