CSGRegionQ[reg]

如果区域 reg 是有效的 CSGRegion 对象，则给出 True，否则给出 False.

范例

打开所有单元 关闭所有单元

基本范例  (2)

有效的二维 CSG 区域：

Wolfram Language code: CSGRegion["Union", {Disk[], Rectangle[]}]
Wolfram Language code: CSGRegionQ[%]

三维：

Wolfram Language code: CSGRegion["Union", {Ball[], Cuboid[]}]
Wolfram Language code: CSGRegionQ[%]

范围  (3)

CSGRegionQ 适用于 CSG 区域相交：

Wolfram Language code: CSGRegion["Intersection", {Ball[], Cuboid[]}]
Wolfram Language code: CSGRegionQ[%]

合集：

Wolfram Language code: CSGRegion["Union", {Ball[], Cuboid[]}];
Wolfram Language code: CSGRegionQ[%]

差值：

Wolfram Language code: CSGRegion["Difference", {Ball[], Cuboid[]}];
Wolfram Language code: CSGRegionQ[%]

CSGRegionQ 可处理 1-level CSG 区域：

Wolfram Language code: CSGRegion["Intersection", {Ball[], Cuboid[]}]
Wolfram Language code: CSGRegionQ[%]

嵌套的 CSG 区域：

Wolfram Language code: CSGRegion["Intersection", {Ball[], CSGRegion["Union", {Ball[], Cuboid[]}]}];
Wolfram Language code: CSGRegionQ[%]

与两个以上区域的交集：

Wolfram Language code: CSGRegion["Intersection", {Ball[], Ball[], Cuboid[], Ball[]}];
Wolfram Language code: CSGRegionQ[%]

CSGRegionQ 可处理二维 CSG 区域：

Wolfram Language code: CSGRegion["Intersection", {Disk[], Rectangle[]}]
Wolfram Language code: CSGRegionQ[%]

三维：

Wolfram Language code: CSGRegion["Intersection", {Ball[], Cuboid[]}];
Wolfram Language code: CSGRegionQ[%]

维：

Wolfram Language code: CSGRegion["Intersection", {Ball[{0, 0, 0, 0}], Ball[{1, 0, 1, 0}]}];
Wolfram Language code: CSGRegionQ[%]

属性和关系  (4)

CSGRegionQ 是 RegionQ 的特例：

Wolfram Language code: Subscript[ℛ, 1] = CSGRegion["Intersection", {Ball[], Cuboid[]}]; Subscript[ℛ, 2] = ConvexHullMesh[RandomReal[1, {10, 2}]];
Wolfram Language code: CSGRegionQ /@ {Subscript[ℛ, 1], Subscript[ℛ, 2]}
Wolfram Language code: RegionQ /@ {Subscript[ℛ, 1], Subscript[ℛ, 2]}

CSGRegion 的 BoundedRegionQ 结果总是为真：

Wolfram Language code: ℛ = CSGRegion["Intersection", {Ball[], Cuboid[]}];
Wolfram Language code: {CSGRegionQ[ℛ], BoundedRegionQ[ℛ]}

CSGRegion 的 ConstantRegionQ 结果总是为真：

Wolfram Language code: ℛ = CSGRegion["Intersection", {Ball[], Cuboid[]}];
Wolfram Language code: {CSGRegionQ[ℛ], ConstantRegionQ[ℛ]}

CSGRegion 是实心的：

Wolfram Language code: ℛ = CSGRegion["Intersection", {Ball[], Cuboid[]}];
Wolfram Language code: {CSGRegionQ[ℛ], SolidRegionQ[ℛ]}
