Fit street heights to graph.
@example:
# Settings class specifying parameters for automatically determining street heights.
settings = GenerateBridgeSettings()
settings.setObjectAttributeForAbsoluteHeight("none")
settings.setLevelHeight(50)
settings.setObjectAttributeForLevel("layer")
settings.setRampMaximumSlope(0.01)
settings.setLockNonZeroHeights(False)
settings.setAllowTunnels(True)
settings.setBridgeJoinPreference(2)
settings.setUseVisibleTerrain(False)
settings.setOnlyApplyLevelWhenStreetsCross(False)
segments = ce.getObjectsFrom(ce.scene, ce.isGraphSegment)
ce.generateBridges(segments, settings)
此处定义的方法如下:
getAllowTunnels
getAllowTunnels(self):
Gets AllowTunnels field. Allow tunnels (streets below zero height).
@return: Value of AllowTunnels field. [True/False]
getBridgeJoinPreference
getBridgeJoinPreference(self):
Gets BridgeJoinPreference field. 0 to 10; where 0 = disconnect bridges, and 10 = link bridges together.
@return: Value of BridgeJoinPreference field. [float]
getLevelHeight
getLevelHeight(self):
Gets LevelHeight field. Vertical distance between two crossing streets.
@return: Value of LevelHeight field. [float]
getLockNonZeroHeights
getLockNonZeroHeights(self):
Gets LockNonZeroHeights field. Do not change height of nodes with non-zero position.
@return: Value of LockNonZeroHeights field. [True/False]
getObjectAttributeForAbsoluteHeight
getObjectAttributeForAbsoluteHeight(self):
Gets ObjectAttributeForAbsoluteHeight field. (optional) If the object attribute exists, it is used to set the total height and Level Height is discarded.
@return: Value of ObjectAttributeForAbsoluteHeight field. [str]
getObjectAttributeForLevel
getObjectAttributeForLevel(self):
Gets ObjectAttributeForLevel field. (optional) If the object attribute exists, it is used to set the level i.e. total height equals Level Height multiplied with this attribute.
@return: Value of ObjectAttributeForLevel field. [str]
getOnlyApplyLevelWhenStreetsCross
getOnlyApplyLevelWhenStreetsCross(self):
Gets OnlyApplyLevelWhenStreetsCross field. Only use the Level object attribute when streets cross.
@return: Value of OnlyApplyLevelWhenStreetsCross field. [True/False]
getRampMaximumSlope
getRampMaximumSlope(self):
Gets RampMaximumSlope field. Maximum slope of (vertical climb per horizontal unit).
@return: Value of RampMaximumSlope field. [float]
getUseVisibleTerrain
getUseVisibleTerrain(self):
Gets UseVisibleTerrain field. Treat all heights as relative above terrain (if any).
@return: Value of UseVisibleTerrain field. [True/False]
