Detailed Description

A MultiTool that applies a mouse-controlled transform to a subset.

Left mouse button controls a translation, center mouse button controls a scaling, and right mouse button controls a rotation.

Definition at line 378 of file mesh_grob_tool.h.

Member Function Documentation

◆ clear_subset()

virtual void OGF::MeshGrobTransformTool::clear_subset ( )

protectedvirtual

Clears the state variables that store the subset.

Default implementation does nothing.

Reimplemented in OGF::MeshGrobTransformComponent.

◆ grab()

void OGF::MeshGrobTransformTool::grab ( const RayPick & p_ndc )

override

◆ mesh_grob()

MeshGrob* OGF::MeshGrobTransformTool::mesh_grob ( ) const

inline

Gets the MeshGrob this MeshGrobTransformTool operates on.

Returns: a pointer to the MeshGrob

Definition at line 409 of file mesh_grob_tool.h.

◆ pick_subset()

virtual void OGF::MeshGrobTransformTool::pick_subset	(	MeshGrobTransformSubset *	tool,
		const RayPick &	rp
	)

protectedpure virtual

Gets the subset by picking.

This function is called when the mouse is pressed. It is meant to be overloaded in derived classes, to memorize the picked subset in some state variables.

Parameters

[in]	tool	a pointer to the MeshGrobTransformSubset
[in]	rp	a RayPick as returned by RenderArea events

Implemented in OGF::MeshGrobTransformFacet, OGF::MeshGrobCopyComponent, and OGF::MeshGrobTransformComponent.

◆ release()

void OGF::MeshGrobTransformTool::release ( const RayPick & p_ndc )

overridevirtual

The event handler for mouse release events.

Parameters

[in] value a const reference to the picking event

Reimplemented from OGF::Tool.

◆ transform_subset()

virtual void OGF::MeshGrobTransformTool::transform_subset ( const mat4 & M )

protectedpure virtual

Applies a 3D transform to the subset.

Parameters

[in] M a const reference of the homogeneous coordinates matrix of the transform.

Implemented in OGF::MeshGrobTransformFacet, OGF::MeshGrobCopyComponent, and OGF::MeshGrobTransformComponent.

◆ update_transform_subset()

void OGF::MeshGrobTransformTool::update_transform_subset ( const mat4 & M )

inlineprotected

Applies the transform M to the subset.

The transform /p M is applied to the subset as it was when grab() was called (any previously applied transform is canceled).

Parameters

[in] M the transform to be applied

Definition at line 422 of file mesh_grob_tool.h.

Member Data Documentation

◆ prev_inverse_transform_

mat4 OGF::MeshGrobTransformTool::prev_inverse_transform_

protected

The inverse of the previous transform.

It is used when the transform is updated, to undo the previous transform.

Definition at line 465 of file mesh_grob_tool.h.
