Hi, Like some users such as Mostafa, I have trouble using functions when changing axes. For example, when the Z-axis is placed vertically. How can functions such as "ScreenVectorIntersectWithPlaneXZ" or "rotatearound" be used when the Z axis is set vertically or the "up" property is set to (0,0,1)? Are there alternative functions or is a way to use them correctly?

hi shine , I have 2 freeform such as electrical device , I defined 2 point by two sphere for connection point but these spheres are invisible , I want to connect line (as wire) between two free form connection point at runtime bye mouse. how detect the position of that sphere for add line node?

Hi, I have several invisible object ( such as TGLsphere) as connection points and I want to pick these objects and draw wires ( such as wire example ) How can I do that?

Hi, I have a project and I want to add undo/Redo feature to it, how can do that easily? how can use GizmoEx component for undo/redo ? I looket at GizmoEx example but Don't understand usage method.

Hi, How can I use opengl commands by GLDirectOpenGL correctly? I know I must use OnRender event but my commands not work completely, for example for display a triangle with three colors at the vertices I use this code : procedure TForm1.GLDirectOpenGL1Render(Sender: TObject; var rci: TGLRenderContextInfo); begin glBegin(GL_TRIANGLES); glColor3f(1, 0, 0); glVertex3f( 0.0, 1.0, 0.0); glColor3f(0, 1, 0); glVertex3f(-1.0,-1.0, 0.0); glColor3f(0, 0, 1); glVertex3f( 1.0,-1.0, 0.0); glEnd; end; But I have...

Hi, How can I use opengl commands by GLDirectOpenGL? thanks.

Hi, Why is the CSG function very slow compared to other software? Isn't it possible to speed it up? For example, in my computer, the operation of subtracting two objects, each with a volume of about 900 meshes, takes about 7,8 seconds, while the same operation in 3DS Max software takes less than a second. Is there a way to increase this speed?

Hi Jerome.D, Thank you for your answer. In this example ( Branches/Examples/path/Findpath3D), a behavior has already been defined (at design time) for each object, such as the sphere. But my objects are created at Run time, and I want to know when they are created whether they have collision with other objects in my scene or not. (My objects are FreeForm) How can I define a behavior for objects that are generated at Run time and how can I assign a Manager (such as DCEManager1) to each behavior I...
