Detailed Description

Composite container of graphics objects.

The client adds the graphics objects to the container through push(gobj*).

Very simple pointer memory management is supported with nuke() and the destructor calling delete() on the pointers. By default it is assumed that objects pushed are contructed from new operator and are memory managed by this class.

If cleanup is set to false (explicityly or at construction time) then this class assumes the graphics pointers are managed outside of this class.

There is a global graphics pointer which is like a universal graphics stream. Clients write to the container by pushing back gobj's. This can be used to pass geometry as well as a storage place for the gobj's to be evaluated at a later date.

Member Function Documentation

void gobjContainer::displaylist

(

uintc

id

)

Convert this graphics list into a display list.

This destroys and realizes the current geometry and is a non reversible operation. cleanup is set to true. The id is the compiled lists id.

gobjglCallList<GLuint>* gobjContainer::displaylistcreatenew

(

uint

id

)

Compile the list of graphics to a display list.

The new operator called so the client owns the object.

void gobjContainer::draw

(

[virtual]

Draws vg[i].

Implements gobj.

Reimplemented in pathlinesegdraw, tessD2draw02points< TESS, PT >, gobjContainerPrePost, tessD1draw01points< TESS, PT >, tessD1draw01lines< TESS, PT >, tessD1draw01linesmulticolor< TESS, PT >, and tessD1draw01simplexindexes< TESS, PT >.
