@jklqwe111 这个是 DisplayListPrimitive.h的源代码

#include <opencsg.h>

namespace OpenCSG {

    class DisplayListPrimitive: public Primitive  {
    public:
        /// An object of this class contains the OpenGL id of a display
        /// list that is compiled by the application. render() just invokes
        /// this display list.
        /// Operation and convexity are just forwarded to the base Primitive class.
        DisplayListPrimitive(unsigned int displayListId_, Operation, unsigned int convexity);

        /// Sets the display list id
        void setDisplayListId(unsigned int);
        /// Returns the display list id
        unsigned int getDisplayListId() const;

        /// Calls the display list.
        virtual void render();

    private:
        unsigned int mDisplayListId;
    };

} // namespace OpenCSG

这个是DisplayListPrimitive.cpp的源代码

#include <GL/glew.h>
#include "displaylistPrimitive.h"
#include <OpenCSG.h>

namespace OpenCSG {

    DisplayListPrimitive::DisplayListPrimitive(unsigned int i , Operation o, unsigned int c)

    {
        mDisplayListId = i;
    }

    void DisplayListPrimitive::setDisplayListId(unsigned int i) {
        mDisplayListId = i;
    }

    unsigned int DisplayListPrimitive::getDisplayListId() const {
