Method Detail

delayedInit

public void delayedInit(SamplingParams params)

delayedInitNative

protected void delayedInitNative(Scene scene)

getTileFetcher

public TileFetcher getTileFetcher()

Return the tile fetcher being used. Must be called after initialization.

setBaseDrawPriority

public void setBaseDrawPriority(int drawPriority)

Set the base priority values for produced tiles.
The system will use a range of values to deal with overlaps. This is the base value.

setDrawPriorityPerLevel

public void setDrawPriorityPerLevel(int drawPriority)

Set the draw priority offset per level.
We use this number when calculating the draw priority for a particular level. This is multiplied by the level number. By default it's 1.
This is useful if we want to insert geometry between the levels and have it be masked by high levels. We do this with vector tile data.

setColor

public void setColor(int color)

Set the color used by the geometry.

Parameters:

color - Color in Android format, including alpha.

setColor

public void setColor(float r,
                     float g,
                     float b,
                     float a,
                     ChangeSet changes)

Set the color used by the geometry. Color values range from 0 to 1.0. You must specify all four values. Alpha controls transparency.

Parameters:

r - Red component.

g - Green component.

b - Blue component.

a - Alpha component.

setZBufferWrite

public void setZBufferWrite(boolean val)

Write to the z buffer when rendering. On by default.

setZBufferRead

public void setZBufferRead(boolean val)

Read from the z buffer when rendering. Off by default.

setShader

public void setShader(Shader shader)

Shader to use for rendering the image frames. If not set we'll pick the default visual shader.

setShaderID

public void setShaderID(long shaderID)

Shader to use for rendering the image frames. If not set we'll pick the default visual shader.

setRenderTarget

public void setRenderTarget(RenderTarget target)

An optional render target for this loader.
The loader can draw to a render target rather than to the screen. You use this in a multi-pass rendering setup.

setRenderTargetID

public void setRenderTargetID(long targetID)

An optional render target for this loader.
The loader can draw to a render target rather than to the screen. You use this in a multi-pass rendering setup.

setImageFormat

public void setImageFormat(RenderController.ImageFormat imageFormat)

Set the image format for internal imagery storage.
OpenGL ES offers us several image formats that are more efficient than 32 bit RGBA, but they're not always appropriate. This property lets you choose one of them. The 16 or 8 bit ones can save a huge amount of space and will work well for some imagery, most maps, and a lot of weather overlays.
Be sure to set this at layer creation, it won't do anything later on.

setImageFormatNative

protected void setImageFormatNative(int imageFormat)

setBorderTexel

public void setBorderTexel(int borderTexel)

Number of border texels to set up around image tiles.
For matching image tiles along borders in 3D (probably the globe) we resample the image slightly smaller than we get and make up a boundary around the outside. This number controls that border size.
By default this is 1. It's safe to set it to 0 for 2D maps and some overlays.

makeLoaderReturn

protected LoaderReturn makeLoaderReturn()

Description copied from class: QuadLoaderBase

The subclasses fill this in with the loaderReturn that they need.

Overrides:

makeLoaderReturn in class QuadLoaderBase

changeTileInfo

protected void changeTileInfo(TileInfoNew[] newTileInfo)

Change the tile sources all at once. This also forces a reload.
