Header:#include <UnigineDecals.h>
Inherits:Decal

This class describes how to create and modify proj decals.

DecalProj Class

Members


static DecalProjPtr create(float radius, float fov, float aspect, const char * name)

Constructor. Creates a new projected decal with the given properties.

Arguments

  • float radius - The height of the projection pyramid along the Z axis, in units.
  • float fov - The field of view of the decal's projector, in degrees.
  • float aspect - The aspect ratio of the decal, in units.
  • const char * name - A material of the decal.

Ptr<DecalProj> cast(const Ptr<Decal> & base)

Arguments

  • const Ptr<Decal> & base

Ptr<DecalProj> cast(const Ptr<Node> & node)

Arguments

  • const Ptr<Node> & node

void setAspect(float aspect)

Sets the new aspect ratio of the decal, in units.

Arguments

  • float aspect - The aspect ratio of the decal, in units. If a negative value is provided, 0 will be used instead.

float getAspect()

Returns the current aspect ratio of the decal.

Return value

The aspect ratio of the decal, in units.

void setFov(float fov)

Sets a new field of view of the decal's projector.

Arguments

  • float fov - A field of view of the decal's projector, in degrees. The provided value will be clamped in the range [1;90].

float getFov()

Returns the current field of view of the decal's projector.

Return value

The field of view of the decal's projector, in degrees.

Math::mat4 getProjection()

void setRadius(float radius)

Sets a new height of the projection pyramid along the Z axis, in units.

Arguments

  • float radius - A height of the projection pyramid along the Z axis, in units. If a too small value is provided, 1E-6 will be used instead.

float getRadius()

Returns the current height of the projection pyramid along the Z axis, in units.

Return value

The height of the projection pyramid along the Z axis, in units.

void setZNear(float znear)

Sets a distance to the near clipping plane of the decal.

Arguments

  • float znear - A new distance to the near clipping plane, in units. If a negative value is provided, 0 will be used instead.

float getZNear()

Returns the distance to the near clipping plane of the decal.

Return value

The distance to the near clipping plane, in units.
