Web1 de fev. de 2024 · OpenGL provides matrix stacks specifically for this purpose. In this case, use the ModelView matrix stack. A typical OpenGL application first sets the matrix mode with a call to glMatrixMode (GL_MODELVIEW) and loads a viewing transform, perhaps with a call to gluLookAt ().

You must ensure that you do not Pop() more times than you Push() . Also, while this matrix stack does not have an explicit size limit, if you Push() more times than you Pop() , then you can eventually run out of memory …

WebMatrix stack JOML also features an interface that resembles the matrix stack from legacy OpenGL. This allows you to use all of the legacy OpenGL matrix stack operations even in modern OpenGL applications, but without the otherwise necessary JNI calls into the graphics driver. Note that JOML does not interface in any way with the OpenGL API.

WebglPushMatrix pushes a copy of the current matrix onto the current stack, while glPopMatrix pops the top of the stack (changing the current matrix to whatever was just below the top). Note: the stack depth limited (though at least 32 for GL_MODELVIEW and at least 2 for the other modes including GL_PROJECTION ), so be careful how many things you push. WebOpenGL has a modelviewmatrix stack which is used to support hierarchical modelling. The modelview matrix stack is at least 32 levels deep. OpenGL also has a projection matrix stack, which is at least 2 levels deep, but is not needed for hierarchical modelling.
