Types

type Brightness

type Brightness int

func (Brightness) ScaleRGB

func (b Brightness) ScaleRGB(r renderer.RGB) renderer.RGB

type ClientVideoMap

type ClientVideoMap struct {
	sim.VideoMap
	CommandBuffer renderer.CommandBuffer
}

ClientVideoMap extends sim.VideoMap with client-side rendering capabilities.

func BuildClientVideoMaps

func BuildClientVideoMaps(maps []sim.VideoMap) []ClientVideoMap

BuildClientVideoMaps converts []sim.VideoMap to ClientVideoMaps, generating CommandBuffers along the way.

type ERAMVideoMap

type ERAMVideoMap struct {
	sim.ERAMMap
	CommandBuffer renderer.CommandBuffer
}

func BuildERAMClientVideoMaps

func BuildERAMClientVideoMaps(maps []sim.ERAMMap) []ERAMVideoMap

TODO: Eventually combine them

type ScopeTransformations

type ScopeTransformations struct {
	// contains filtered or unexported fields
}

func GetScopeTransformations

func GetScopeTransformations(paneExtent math.Extent2D, magneticVariation float32, nmPerLongitude float32,
	center math.Point2LL, rangenm float32, rotationAngle float32) ScopeTransformations

GetScopeTransformations returns a ScopeTransformations object corresponding to the specified radar scope center, range, and rotation angle.

func (*ScopeTransformations) LatLongFromWindowP

func (st *ScopeTransformations) LatLongFromWindowP(p [2]float32) math.Point2LL

LatLongFromWindowP transforms a point p in window coordinates to latitude-longitude.

func (*ScopeTransformations) LatLongFromWindowV

func (st *ScopeTransformations) LatLongFromWindowV(v [2]float32) math.Point2LL

LatLongFromWindowV transforms a vector in window coordinates to a vector in latitude-longitude coordinates.

func (*ScopeTransformations) LoadLatLongViewingMatrices

func (st *ScopeTransformations) LoadLatLongViewingMatrices(cb *renderer.CommandBuffer)

LoadLatLongViewingMatrices adds commands to the provided command buffer to load viewing matrices so that latitude-longiture positions can be provided for subsequent vertices.

func (*ScopeTransformations) LoadWindowViewingMatrices

func (st *ScopeTransformations) LoadWindowViewingMatrices(cb *renderer.CommandBuffer)

LoadWindowViewingMatrices adds commands to the provided command buffer to load viewing matrices so that window-coordinate positions can be provided for subsequent vertices.

PixelDistanceNM returns the space between adjacent pixels expressed in nautical miles.

func (*ScopeTransformations) WindowFromLatLongP

func (st *ScopeTransformations) WindowFromLatLongP(p math.Point2LL) [2]float32

WindowFromLatLongP transforms a point given in latitude-longitude coordinates to window coordinates, snapped to a pixel center.

type WeatherRadar

type WeatherRadar struct {
	// contains filtered or unexported fields
}

WeatherRadar provides functionality for fetching precipitation data from the server and displaying it in radar scopes.
