Lecture Autodesk inventor 3D geometric transformations. In this chapter, students will be able to understand kinds of transformations translation, rotation, reflection, scaling, shearing; AutoCAD transformation commands.
3D Geometric Transformations Kinds of Transformations Translation Rotation Reflection Scaling Shearing NOTES: • These transformations are an important component of computer graphics programming • Each transformation type can be expressed in a (4 x 4) matrix, called the Transformation Matrix Translation Moving the object from one position to another Rotation Rotating the object about an axis Reflection Mirroring an object about a plane Scaling Reducing or enlarging the object Shearing Moving selected vertices of an object linearly along an axis AutoCAD Transformation Commands Geometric Transformation Translation AutoCAD Command Move and COpy Rotation ROtate and ROTATE3D Reflection MIrror and MIRROR3D Scaling SCale Shearing STRETCH Rotations – Positive and Negative Rotations – Positive about x,y,z Multiple Rotations 3D Transformations The End ... axis AutoCAD Transformation Commands Geometric Transformation Translation AutoCAD Command Move and COpy Rotation ROtate and ROTATE3D Reflection MIrror and MIRROR3D Scaling SCale Shearing STRETCH...Kinds of Transformations Translation Rotation Reflection Scaling Shearing NOTES: • These transformations are an important component of computer graphics...
