MaplyGeomModelGPUInstance

Objective-C

@interface MaplyGeomModelGPUInstance : NSObject

Swift

class MaplyGeomModelGPUInstance : NSObject

Sometimes we don’t know how many instances there will be of a model until some logic runs on the GPU. We can then take that number and run that number of instances of the given model. [Metal only]

  • The model to instance

    Declaration

    Objective-C

    @property (nonatomic, strong, nullable) MaplyGeomModel *model;

    Swift

    var model: MaplyGeomModel? { get set }

  • Texture to derive the number of instances from (picked out of the highest, smallest level)

    Declaration

    Objective-C

    @property (nonatomic, nullable) MaplyTexture *numInstSource;

    Swift

    var numInstSource: MaplyTexture? { get set }

  • Need a shader to pull the number of instances out of a texture and shove them in the indirect buffer

    Declaration

    Objective-C

    @property (nonatomic, nullable) MaplyShader *numInstShader;

    Swift

    var numInstShader: MaplyShader? { get set }

  • Shader to run over for this instance

    Declaration

    Objective-C

    @property (nonatomic, nullable) MaplyShader *shader;

    Swift

    var shader: MaplyShader? { get set }
