Question

使用JOGL时遇到问题。这是代码和错误消息：

@Override
    public void display(GLAutoDrawable drawable) {
        GL2 gl = drawable.getGL().getGL2();
        gl.glLoadIdentity();
        gl.glClear(GL2.GL_COLOR_BUFFER_BIT | GL2.GL_DEPTH_BUFFER_BIT);
        gl.glBindTexture(GL2.GL_TEXTURE_2D, tex);
        gl.glEnableClientState(GL2.GL_VERTEX_ARRAY);
        gl.glEnableClientState(GL2.GL_TEXTURE_COORD_ARRAY);
        gl.glEnableClientState(GL2.GL_NORMAL_ARRAY);
        gl.glVertexPointer(3, GL2.GL_FLOAT, 0, vertices);
        gl.glTexCoordPointer(3, GL2.GL_FLOAT, 0, texCoords);
        gl.glTexCoordPointer(3, GL2.GL_FLOAT, 0, normals);
        gl.glDrawArrays(gl.GL_QUADS, 0, 4); // error
        for (Model.VerticesDescriptor vd : model.vd) {
            //if (vd.POLYTYPE == vd.POLY_TYPE_TRIANGLES) gl.glDrawArrays(gl.GL_TRIANGLES, vd.START, vd.END); // error
            //if (vd.POLYTYPE == vd.POLY_TYPE_QUADS) gl.glDrawArrays(gl.GL_QUADS, vd.START, vd.END); // error
            //else if (vd.POLYTYPE == vd.POLY_TYPE_POLYGON) gl.glDrawArrays(gl.GL_POLYGON, vd.START, vd.END); // error
        }
        gl.glDisableClientState(GL2.GL_VERTEX_ARRAY);
        gl.glDisableClientState(GL2.GL_TEXTURE_COORD_ARRAY);
        gl.glDisableClientState(GL2.GL_NORMAL_ARRAY);
    }

这个问题可以连接什么？这是我正在制作缓冲区的代码（位于init函数中）：

vertices = Buffers.newDirectFloatBuffer(model.vertices.length);
        vertices.put(model.vertices).position(0);

        texCoords = Buffers.newDirectFloatBuffer(model.texCoords.length);
        texCoords.put(model.texCoords).position(0);

        normals = Buffers.newDirectFloatBuffer(model.normals.length);
        normals.put(model.normals).position(0);

这些缓冲区中有~5000个元素

Answer 1

所以，错误就在这一行

gl.glTexCoordPointer(3, GL2.GL_FLOAT, 0, normals);

我把它改成了

gl.glNormalPointer(GL2.GL_FLOAT, 0, normals);

现在一切正常
