static DecalOrthoPtr create ( float radius, float width, float height, const char * material ) #

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

Arguments

• float radius - The height of the projection box along the Z axis, in units.
• float width - The length of the projection box along the X axis, in units.
• float height - The length of the projection box along the Y axis, in units.
• const char * material - A material of the decal.

void setHeight ( float height ) #

Sets a new length of the projection box along the Y axis.

Arguments

• float height - The length of the projection box along the Y axis, in units. If a negative value is provided, 0 will be used instead.

float getHeight ( ) #

Returns the current length of the projection box along the Y axis.

Return value

The length of the projection box along the Y axis, in units.

Math::mat4 getProjection ( ) #

Returns the projection matrix.

Return value

The projection matrix of the decal.

void setRadius ( float radius ) #

Sets a new height of the projection box along the Z axis.

Arguments

• float radius - A height of the projection box 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 box along the Z axis.

Return value

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

void setWidth ( float width ) #

Sets the new length of the projection box along the X axis.

Arguments

• float width - The length of the projection box along the X axis, in units. If a negative value is provided, 0 will be used instead.

float getWidth ( ) #

Returns the current length of the projection box along the X axis, in units.

Return value

The length of the projection box along the X axis, in units.

void setZNear ( float znear ) #

Sets a new value of the near clipping plane.

Arguments

• float znear - A value of the near clipping plane, ranging from 0 to 1. If a negative value is provided, 0 will be used instead.

float getZNear ( ) #

Returns the value of the near clipping plane.

Return value

The value of the near clipping plane, ranging from 0 to 1.

static int type ( ) #

Returns a type identifier.

Return value

Type identifier.
