SurfaceImage

open class SurfaceImage : AbstractSurfaceRenderable

Decal that projects an image (CPU-loaded) or a Texture (GPU-resident) onto the terrain over sector. Use the imageSource constructor for the typical bitmap/URL path (the texture is resolved via RenderContext.getTexture and cached in RenderResourceCache); use the texture constructor when the data already lives on the GPU — e.g. the output of a render-to-texture pass — to skip the upload round-trip entirely.

When both imageSource and texture are set, texture takes precedence.

Properties

displayName

open override var displayName: String?

imageOptions

var imageOptions: ImageOptions?

imageSource

var imageSource: ImageSource?

Image-source path: image is uploaded by RenderResourceCache on first use and cached.

isEnabled

open override var isEnabled: Boolean

isPickEnabled

open override var isPickEnabled: Boolean

pickDelegate

open override var pickDelegate: Any?

sector

val sector: Sector

texture

var texture: Texture?

GPU-direct path: texture is sampled in place by the surface drawable, no upload. Caller owns the lifecycle. Setting this overrides any imageSource resolution.

zOrder

open override var zOrder: Double
