from panda3d.core import DepthBiasAttrib
class DepthBiasAttrib


Bases: RenderAttrib

This is a special kind of attribute that instructs the graphics driver to apply an offset or bias to the generated depth values for rendered polygons, before they are written to the depth buffer.

This class replaces the old DepthOffsetAttrib, which had a more limited parameterization. The differences are: - The sign of the factor parameter was inverted. - The slope and constant factors are specified separately. - The factors are specified as floating-point instead of integer. - There is a new clamp parameter.

Nested DepthBiasAttrib values accumulate; that is, a DepthBiasAttrib with a value of 1 beneath another DepthBiasAttrib with a value of 2 presents a net offset of 3. (A DepthBiasAttrib will not, however, combine with any other DepthBiasAttribs with a lower override parameter.)

New in version 1.11.0.

Inheritance diagram

Inheritance diagram of DepthBiasAttrib

property clamp float

Returns the maximum (or minimum, if negative) value of the bias. If zero, no clamping is performed.

property class_slot int
property constant_factor float

Returns the constant factor.

static get_class_slot() int
static get_class_type() TypeHandle
static make(slope_factor: float, constant_factor: float, clamp: float) RenderAttrib

Constructs a new DepthBiasAttrib object that indicates the slope factor, constant factor, and an optional clamping value.

static make_default() RenderAttrib

Returns a RenderAttrib that corresponds to whatever the standard default properties for render attributes of this type ought to be.

property slope_factor float

Returns the slope factor.
