The current matrix (see glMatrixMode) is multiplied by this scale matrix, with the product replacing the current matrix.
"without using the glTranslatef function via GLUT" GLUT does not provide glTranslatef.0f,0. glPushMatrix () glTranslatef (dx, dy, dz); glVertex3f (x, y, z); glPopMatrix () is equivalent to this: glVertex3f (x+dx, y+dy, z+dz); regardless of any previous transformations: If you need to apply multiple transformations to the data, compose them into a matrix then use the matrix to transform the data. After reading this chapter, you'll be able to do the following: View a geometric model in any orientation by transforming it in three-dimensional space.0, 2. 답부터 말하자면 View transformation 결과에는 두 방법 모두 .

All tutors are evaluated by Course Hero as an expert in their subject area. 구문 void WINAPI glRotatef( GLfloat angle, GLfloat x, GLfloat y, GLfloat z ); 매개 변수. You have to swap the translation and rotation operation: glRotatef (angle, 0. 화이트 샌즈 Formula: X = x + tx Y = y + ty where tx and ty are translation coordinates The … · 3 Answers. glTranslatef shouldn't work between begin/end (although the driver may let you, it's not supported in the specs ). Take care that the code may be old, broken or not even use PyOpenGL. – datenwolf. But glTranslates sees only a small number, so the shift is miniscule (one pixel) and hence you think nothing did happen. With the help of GLUquadriObj we create spherical and cylindrical structure and with the help of other basic OpenGL function like glRotatef, glTranslatef we assemble the objects into 3D robot.
