Inheritance diagram for BaseDraw:

[legend]

Detailed Description

Represents a view window that can be drawn into.

Note: Has to be created with Alloc() and destroyed with Free(). Use AutoAlloc to automate the allocation and destruction based on scope.

Warning: The BaseDraw parameters must only be accessed with GetParameter() / SetParameter(), not directly using the data container. GetParameterData() convenience method can be used to get parameters.

Parameters

[in]

zoffset

Sets the current Z buffer offset. Use this to for example draw lines over shaded polygons in front of the screen.
A higher zoffset value means a higher draw priority in the Z buffer. For example:

shaded polygon (level 0)
unselected edges (level 2)

◆ SetMatrix_Screen() [3/3]

◆ SetMatrix_Matrix() [1/2]

void SetMatrix_Matrix	(	BaseObject *	op,

Sets the transformation matrix to the given matrix mg.
The transformation matrix should transform coordinates passed to the draw functions into world coordinates.
For example for an object generator with local handle vectors the global matrix, or even better the matrix returned by BaseDrawHelp::GetMg(), should be used.
In case of a particle system, which calculates all its particles in global space, a unit matrix can be passed because the vectors are already in global space. Basically the matrix that transforms the vectors into global space should be passed.

Parameters

[in]	op	A scene object or nullptr. If an object pointer is passed this is used to compare with an internal pointer to the last passed object pointer. If the pointers differ no matrix comparison is required internally. Used for performance reasons. The caller owns the pointed object.
[in]	mg	The new transformation matrix.

◆ SetMatrix_Matrix() [2/2]

void SetMatrix_Matrix	(	BaseObject *	op,
		const Matrix &	mg,
