Detailed Description

Render simple shapes for debugging purposes.

Note

Methods are static to easy debug like oe::scene::Debug::aabb

Member Function Documentation

aabb()

static void oe::render::Debug::aabb ( const oe::scene::AABB &  bbox, const glm::vec3 &  color = glm::vec3(1.0)  )

static

Draw a bounding box.

Parameters

bbox	Bounding box
color	Box color

axis()

static void oe::render::Debug::axis ( const float &  length = 1.0f, const float &  arrow_size = 0.1f  )

static

Draw origin axis.

Parameters

length	line length
arrow_size	arrow thickness

box()

static void oe::render::Debug::box ( const glm::vec3 &  min, const glm::vec3 &  max, const glm::vec3 &  color = glm::vec3(1.0)  )

static

Draw a box between two corners.

Parameters

min	Box bottom corner
max	Box top corner
color	Sphere color

frustum()

static void oe::render::Debug::frustum ( const oe::scene::Camera &  camera, const glm::vec3 &  color = glm::vec3(1.0)  )

static

Draw the frustum pyramid of a camera.

Parameters

camera	The camera to use as frustum source
color	frustum color

line()

static void oe::render::Debug::line ( const glm::vec3 &  start, const glm::vec3 &  end, const glm::vec3 &  color = glm::vec3(1.0)  )

static

Draw a line between two points.

Parameters

start	first point
end	second point
color	line color

point()

static void oe::render::Debug::point ( const glm::vec3 &  position, const float &  size = 10.0f, const glm::vec3 &  color = glm::vec3(1.0)  )

static

Draw a point.

Parameters

position	Point position
size	Point size in pixels
color	Point color

render()

void oe::render::Debug::render	(	oe::scene::Camera &	camera,
		const bool	flush = true
	)

Render all debug objects and clean buffer.

Parameters

flush

Clean buffer after render (set to false if you need to render debug objects multiple times without cleaning, eg. in VR or in a multipass pipeline)

sphere()

static void oe::render::Debug::sphere ( const glm::vec3 &  center, const float &  radius, const glm::vec3 &  color = glm::vec3(1.0)  )

static

Draw a sphere.

Parameters

center	Sphere position
radius	Sphere radius
color	Sphere color

tbn()

static

Render vertex TBN (Tangent, bi-tangent, normal)

Note

Colors meaning are: normal=WHITE, tangent=YELLOW, bi-tangent=MAGENTA.

static

Draw a transform.

Parameters

model	Transform model matrix
length	line length
arrow_size	arrow thickness
