Detailed Description

Useful routines for rendering primitives when debugging. Compared to the optimized RenderDevice::beginIndexedPrimitives calls used by IFSModel, these routines are slow.

When rendering translucent bounding objects, depth write is automatically disabled. Render from back to front for proper transparency.

const Color4 &  wireColor = Color3::black()
)  [static]
 

Set the solid color or wire color to Color4::clear() to prevent rendering of surfaces or lines.

RenderDevice *  renderDevice,
const Color4 &  solidColor = Color4(1, 0, 1,.5),
const Color4 &  wireColor = Color3::black()

static void G3D::Draw::fastRect2D (  const Rect2D &  rect,
RenderDevice *  rd,
const Color4 &  color = Color3::white()
)  [static]
 

Leaves the renderDevice color and texture coordinates modified. Does not allow custom texture coordinates and only sets texture coordinate 0.

static void G3D::Draw::frustum (  const class GCamera::Frustum &  frustum,
RenderDevice *  rd,
const Color4 &  color = Color4(1,.4f,.4f, 0.2f),

static void G3D::Draw::fullScreenImage (  const class GImage &  im,
RenderDevice *  renderDevice
)  [static]
 

This method is as hideously slow as it is convenient. If you care about performance, make a rectangular texture (without MIPMaps) and draw using that.

static void G3D::Draw::line (  const Line &  line,
RenderDevice *  rd,
const Color4 &  color = Color3::black()
)  [static]

RenderDevice *  rd,
const Color4 &  solidColor = Color4(.2f,.2f, 1,.5f),

static void G3D::Draw::poly2D (  const Array< Vector2 > &  polygon,
RenderDevice *  renderDevice,
const Color4 &  color = Color3::yellow()
)  [static]
 

static void G3D::Draw::poly2DOutline (  const Array< Vector2 > &  polygon,
RenderDevice *  renderDevice,
const Color4 &  color = Color3::yellow()
)  [static]
 

Renders exact corners of a 2D polygon using lines. Assumes you already called push2D().

static void G3D::Draw::ray (  const class Ray &  ray,
RenderDevice *  renderDevice,
const Color4 &  color = Color3::orange(),
float  scale = 1
)  [static]
 

static void G3D::Draw::rect2D (  const class Rect2D &  rect,
RenderDevice *  rd,
const Color4 &  color,
const Rect2D &  texCoord0,
const Rect2D &  texCoord1 = Rect2D::xywh(0, 0, 1, 1),
const Rect2D &  texCoord2 = Rect2D::xywh(0, 0, 1, 1),
const Rect2D &  texCoord3 = Rect2D::xywh(0, 0, 1, 1)
)  [static]
 

Draws the specified rectangle, setting coordinates for the first four texture units as specified.

static void G3D::Draw::rect2D (  const class Rect2D &  rect,
RenderDevice *  rd,
const Color4 &  color = Color3::white(),
const Vector2 &  texCoord0 = Vector2(1, 1),
const Vector2 &  texCoord1 = Vector2(1, 1),
const Vector2 &  texCoord2 = Vector2(1, 1),
const Vector2 &  texCoord3 = Vector2(1, 1)
)  [static]
 

Provided texture coordinates are upper bounds; tex coords will vary from (0,0) to those bounds.

static void G3D::Draw::rect2DBorder (  const class Rect2D &  rect,
RenderDevice *  rd,
const Color4 &  color = Color3::black(),
float  innerBorder = 0,
float  outerBorder = 1
)  [static]
 

Draws a border of size width about the rectangle using polygons (since RenderDevice::LINE_STRIP doesn't guarantee pixel widths).

static void G3D::Draw::sphere (  const Sphere &  sphere,
RenderDevice *  rd,
const Color4 &  solidColor = Color4(1, 1, 0,.5f),
const Color4 &  wireColor = Color3::black()

RenderDevice *  renderDevice,
const Color4 &  color = Color3::green()*.5,
float  scale = 1
)  [static]
 

Renders per-vertex normals as thin arrows. The length of the normals is scaled inversely to the number of normals rendered.

static void G3D::Draw::vertexVectors (  const Array< Vector3 > &  vertexArray,
const Array< Vector3 > &  directionArray,
