Functions ¶
func DrawWaypoints ¶
func DrawWaypoints(ctx *panes.Context, waypoints []av.Waypoint, drawnWaypoints map[string]any, transforms ScopeTransformations, td *renderer.TextDrawBuilder, style renderer.TextStyle, ld *renderer.ColoredLinesDrawBuilder, pd *renderer.ColoredTrianglesDrawBuilder, ldr *renderer.ColoredLinesDrawBuilder, color renderer.RGB)
func GenerateRouteDrawingCommands ¶
func GenerateRouteDrawingCommands(cb *renderer.CommandBuffer, transforms ScopeTransformations, ctx *panes.Context, ld *renderer.ColoredLinesDrawBuilder, pd *renderer.ColoredTrianglesDrawBuilder, td *renderer.TextDrawBuilder, ldr *renderer.ColoredLinesDrawBuilder)
Types ¶
type Brightness ¶
type Brightness int
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.
func (*ScopeTransformations) NormalizedFromWindowP ¶
func (st *ScopeTransformations) NormalizedFromWindowP(p [2]float32) [2]float32
NormalizedFromWindowP transforms a point p in window coordinates to normalized [0,1]^2 coordinates.
func (*ScopeTransformations) PixelDistanceNM ¶
func (st *ScopeTransformations) PixelDistanceNM(nmPerLongitude float32) float32
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.
func (*WeatherRadar) Draw ¶
func (w *WeatherRadar) Draw(ctx *panes.Context, hist int, intensity float32, wxColors [NumWxLevels]renderer.RGB, wxStippleColor renderer.RGB, wxLevelStipple [NumWxLevels]int, active [NumWxLevels]bool, transforms ScopeTransformations, cb *renderer.CommandBuffer)
Draw draws the current weather radar data, if available.
func (*WeatherRadar) HaveWeather ¶
func (w *WeatherRadar) HaveWeather() [NumWxLevels]bool
func (*WeatherRadar) LatestPrecip ¶ added in v0.14.6
LatestPrecip advances the fetch state machine and returns the most recent decoded precipitation blob (may be nil) along with a generation counter that bumps each time the blob changes. Callers that build their own command buffers should rebuild only when the counter changes.
func (*WeatherRadar) Reset ¶ added in v0.15.0
func (w *WeatherRadar) Reset(lg *log.Logger)
Reset clears all cached weather state so that the next tick starts fetching fresh data. It must be called when a new sim is loaded, since nextFetchTime is anchored to the previous sim's calendar date and the cached command buffers belong to the previous sim's weather.
type WxScheme ¶ added in v0.14.6
type WxScheme struct {
// Thresholds is an ascending list of dBZ values; a sample whose dBZ
// exceeds Thresholds[i] but not Thresholds[i+1] maps to level i+1.
Thresholds []byte
}
WxScheme captures how a scope bins NEXRAD dBZ samples into discrete display levels. Scopes (STARS, ERAM, ...) supply their own scheme and use MakeCommandBuffers to turn raw precip data into per-level command buffers.
func (WxScheme) LevelForDBZ ¶ added in v0.14.6
func (WxScheme) MakeCommandBuffers ¶ added in v0.14.6
func (s WxScheme) MakeCommandBuffers(precip *wx.Precip) []*renderer.CommandBuffer
MakeCommandBuffers walks the precip grid once per level, merging horizontal runs of same-level cells into single quads, and returns one CommandBuffer per level (nil entries for empty levels).
