o
- the renderState to compare topublic void setColorWrite(boolean colorWrite)
When color write is enabled, the result of a fragment shader, the
gl_FragColor
, will be rendered into the color buffer
(including alpha).
colorWrite
- Set to true to enable color writing.public void setFaceCullMode(RenderState.FaceCullMode cullMode)
See the RenderState.FaceCullMode
enum on what each value does.
Face culling will project the triangle's points onto the screen
and determine if the triangle is in counter-clockwise order or
clockwise order. If a triangle is in counter-clockwise order, then
it is considered a front-facing triangle, otherwise, it is considered
a back-facing triangle.
cullMode
- the face culling mode.public void setBlendMode(RenderState.BlendMode blendMode)
When blending is enabled, (blendMode
is not RenderState.BlendMode.Off
)
the input pixel will be blended with the pixel
already in the color buffer. The blending operation is determined
by the RenderState.BlendMode
. For example, the RenderState.BlendMode.Additive
will add the input pixel's color to the color already in the color buffer:
Result = Source Color + Destination Color
blendMode
- The blend mode to use. Set to RenderState.BlendMode.Off
to disable blending.public void setBlendEquation(RenderState.BlendEquation blendEquation)
The blending equation determines, how the RGB values of the input pixel
will be blended with the RGB values of the pixel already in the color buffer.
For example, RenderState.BlendEquation.Add
will add the input pixel's color
to the color already in the color buffer:
Result = Source Color + Destination Color
Note: This gets only used in RenderState.BlendMode.Custom
mode.
All other blend modes will ignore this setting.
blendEquation
- The RenderState.BlendEquation
to use.public void setBlendEquationAlpha(RenderState.BlendEquationAlpha blendEquationAlpha)
The alpha blending equation determines, how the alpha values of the input pixel
will be blended with the alpha values of the pixel already in the color buffer.
For example, RenderState.BlendEquationAlpha.Add
will add the input pixel's color
to the color already in the color buffer:
Result = Source Color + Destination Color
Note: This gets only used in RenderState.BlendMode.Custom
mode.
All other blend modes will ignore this setting.
blendEquationAlpha
- The RenderState.BlendEquationAlpha
to use.public void setCustomBlendFactors(RenderState.BlendFunc sfactorRGB, RenderState.BlendFunc dfactorRGB, RenderState.BlendFunc sfactorAlpha, RenderState.BlendFunc dfactorAlpha)
These factors will be multiplied with the color values of the input pixel
and the pixel already in the color buffer, before both colors gets combined by the RenderState.BlendEquation
.
Note: This gets only used in RenderState.BlendMode.Custom
mode.
All other blend modes will ignore this setting.
sfactorRGB
- The source blend factor for RGB components.dfactorRGB
- The destination blend factor for RGB components.sfactorAlpha
- The source blend factor for the alpha component.dfactorAlpha
- The destination blend factor for the alpha component.public void setDepthTest(boolean depthTest)
When depth testing is enabled, a pixel must pass the depth test before it is written to the color buffer. The input pixel's depth value must be less than or equal than the value already in the depth buffer to pass the depth test.
depthTest
- Enable or disable depth testing.public void setDepthWrite(boolean depthWrite)
After passing the depth test
,
a pixel's depth value will be written into the depth buffer if
depth writing is enabled.
depthWrite
- True to enable writing to the depth buffer.public void setWireframe(boolean wireframe)
When in wireframe mode, meshes
rendered in triangle mode
will not be solid, but instead, only the edges of the triangles
will be rendered.
wireframe
- True to enable wireframe mode.public void setPolyOffset(float factor, float units)
factor
- scales the maximum Z slope, with respect to X or Y of the polygonunits
- scales the minimum resolvable depth buffer valuepublic void setStencil(boolean enabled, RenderState.StencilOperation _frontStencilStencilFailOperation, RenderState.StencilOperation _frontStencilDepthFailOperation, RenderState.StencilOperation _frontStencilDepthPassOperation, RenderState.StencilOperation _backStencilStencilFailOperation, RenderState.StencilOperation _backStencilDepthFailOperation, RenderState.StencilOperation _backStencilDepthPassOperation, RenderState.TestFunction _frontStencilFunction, RenderState.TestFunction _backStencilFunction)
Stencil testing can be used to filter pixels according to the stencil buffer. Objects can be rendered with some stencil operation to manipulate the values in the stencil buffer, then, other objects can be rendered to test against the values written previously.
enabled
- Set to true to enable stencil functionality. If false
all other parameters are ignored._frontStencilStencilFailOperation

a front-facing triangle fails the front stencil function._frontStencilDepthFailOperation
