◆ boxShadow()

void OpenGLRenderer::boxShadow	(	glm::vec2	position,
		glm::vec2	size,
		float	blurRadius,
		const AColor &	color
	)

overridevirtual

Draws a rectangle-shaped shadow.

Parameters

position	position
size	rectangle size
blurRadius	blur radius
color	shadow color

Implements IRenderer.

◆ boxShadowInner()

void OpenGLRenderer::boxShadowInner	(	glm::vec2	position,
		glm::vec2	size,
		float	blurRadius,

overridevirtual

Draws inner (inset) rectangle-shaped shadow.

Parameters

position	position
size	rectangle size
blurRadius	blur radius
spreadRadius	spread (offset) radius
borderRadius	border radius of the rectangle.

overridevirtual

Switches drawing to the stencil buffer instead of color buffer.

Stencil pixel is decreased by each affected pixel. Should be called before the popMaskAfter function.

		AAngleRadians	end
	)

overridevirtual

Draws sector in rectangle shape. The sector is drawn clockwise from begin to end angles.

Parameters

brush	brush to use
position	rectangle position (px)
size	rectangle size (px)

The method can be used as mask to ctx.render.roundedRect, creating arc shape.

Implements IRenderer.

◆ string()

void OpenGLRenderer::string	(	glm::vec2	position,
		const AString &	string,
		const AFontStyle &	fs
	)

overridevirtual

Draws string.

Parameters

position	string's top left point
string	string to render
fs	font style (optional)

Note: This function is dramatically inefficient since it does symbol lookup for every character is the string and does GPU buffer allocations. If you want to render the same string for several times (frames), consider using the IRenderer::prerenderString function or high level views (such as ALabel) instead.
