DecalProj (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.

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.

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].

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.

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 getFov ()

Return value

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

float getAspect ()

Returns the current aspect ratio of the decal.

Return value

The aspect ratio of the decal, in units.

float getZNear ()

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

Return value

The distance to the near clipping plane, in units.

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.
