3D Geometric TransformationsKinds of TransformationsTranslationRotationReflectionScalingShearingThese transformations are an important component of computer graphics programmingEach transformation type can be expressed in a (4 x 4) matrix, called the Transformation MatrixNOTES:TranslationMoving the object from one position to anotherRotationRotating the object about an axisReflectionMirroring an object about a planeScalingReducing or enlarging the objectShearingMoving selected vertices of an object linearly along an axisAutoCAD Transformation Commands Geometric Transformation AutoCAD Command Translation Move and COpyRotation ROtate and ROTATE3DReflection MIrror and MIRROR3DScaling SCale Shearing STRETCHRotations – Positive and NegativeRotations – Positive about x,y,zMultiple Rotations3D TransformationsThe End
