Detailed Description

base class for a surface to paint to.

The CRenderTarget subclass this.

—++ On Coordinate System The 2D API uses Y axis downward coordinate; where as the 3D API uses Y axis. Both APIs can be used together. The final world matrix is calculated as thus: finalMatrix = mat2DFinal * matInvertY * mat3DFinal; mat2DFinal is the final matrix by all the 2d api like scale, translate, rotate mat3DFinal is the final matrix by all the 3d api like PushMatrix, TranslateMatrix, etc. Please note, mat3DFinal only takes effect when 3d mode is enabled, such as during rendering head on display or overlays. When you are rendering 3D triangles mixed with 2D GUI, it is good practice to restore mat2DFinal to identity matrix after drawing 2D GUI.

Member Function Documentation

§ beginNativePainting()

void ParaEngine::CPainter::beginNativePainting ( )

native painting is supported by default.

however, one need to call SetUse3DTransform(true) before begin(). this function does nothing here.

§ device()

CPaintDevice * ParaEngine::CPainter::device ( ) const

Returns the paint device on which this painter is currently painting, or 0 if the painter is not active.

See also
isActive()

§ DrawSceneObject()

void ParaEngine::CPainter::DrawSceneObject ( CBaseObject pObj,
int  nOption = 0 
)

draw a scene object

Parameters
objcan be a character or model object.
nOptiondefault to 0, which renders using the transform of the scene object.

§ FromUnitSpaceX()

float ParaEngine::CPainter::FromUnitSpaceX ( float  fUnitspaceX)

get screen space coordinate from a unit space x parameter.

It will take UI scaling into consideration

Parameters
fUnitspaceX[0,1], where 0 is left most, 1 is right most.

§ GetCurMatrix()

const ParaEngine::Matrix4 & ParaEngine::CPainter::GetCurMatrix ( ) const

get current world matrix.

§ GetPendingAssetCount()

int ParaEngine::CPainter::GetPendingAssetCount ( )

number of texture between begin() end() that is not available at the time of drawing.

we generally make the paint device dirty if there is painted with at least one pending asset.

§ GetScaling()

Vector3 ParaEngine::CPainter::GetScaling ( )

get the current world matrix's scaling.

§ InstallFields()

int ParaEngine::CPainter::InstallFields ( CAttributeClass pClass,
bool  bOverride 
)
virtual

this class should be implemented if one wants to add new attribute.

This function is always called internally.

Reimplemented from ParaEngine::IAttributeFields.

§ IsUse3DTransform()

bool ParaEngine::CPainter::IsUse3DTransform ( )

return false by default.

§ LoadBillboardMatrix()

void ParaEngine::CPainter::LoadBillboardMatrix ( )

load a matrix so that everything rendered faces the camera.

it will only do so by a rotation.

§ LoadCurrentMatrix()

void ParaEngine::CPainter::LoadCurrentMatrix ( )

retrieve the current matrix.

§ MultiplyMatrix()

void ParaEngine::CPainter::MultiplyMatrix ( const Matrix4 mat)

multiply the current matrix with the specified matrix.

we use row-major matrix

§ PopMatrix()

void ParaEngine::CPainter::PopMatrix ( )

similar to glPopMatrix() in opengl.

§ PushMatrix()

void ParaEngine::CPainter::PushMatrix ( )

similar to glPushMatrix() in opengl.

§ SetHelperDevice()

void ParaEngine::CPainter::SetHelperDevice ( CPaintDevice val)

currently only used for text size calculation.

§ SetMatrixMode()

void ParaEngine::CPainter::SetMatrixMode ( int  nMode)

similar to glMatrixMode() in opengl.

Parameters
nMode0 is world, 1 is view, 2 is projection. default to 0.

§ SetSpriteTransform()

void ParaEngine::CPainter::SetSpriteTransform ( const Matrix4 pMatrix = NULL)

set the global transform to sprite object.

§ SetSpriteUseWorldMatrix()

void ParaEngine::CPainter::SetSpriteUseWorldMatrix ( bool  bEnable)

set sprite use world matrix.

§ SetUse3DTransform()

void ParaEngine::CPainter::SetUse3DTransform ( bool  bUse3DSpaceTransform)

by default, transforms are in 2d screen space.

However, we can also specify using 3d transform, such as when rendering GUI onto 3D scenes. Call this before begin()

§ setWorldTransform()

void ParaEngine::CPainter::setWorldTransform ( const QTransform matrix,
bool  combine = false 
)

Sets the world transformation matrix.

If combine is true, the specified matrix is combined with the current matrix; otherwise it replaces the current matrix.
