* The point of intersection between the line and the plane, null if the line is parallel to the plane. * lineDirection The direction vector of the line. * planeNormal The normal vector of the plane. * Determines the point of intersection between a plane defined by a point and a normal vector and a line defined by a point and a direction vector. There are vector methods that aren't included but their functions are pretty self explanatory. Here is a method in Java that finds the intersection between a line and a plane. # point-normal planeĭef isect_line_plane_v3_4d(p0, p1, plane, epsilon=1e-6): P_co = mul_v3_fl(plane, -plane / len_squared_v3(plane))įor further reference, this was taken from Blender and adapted to Python.įor clarity, here are versions using the mathutils API (which can be modified for other math libraries with operator overloading). # (divide can be omitted for unit hessian-normal form). If the plane is defined as a 4d vector (normal form), we need to find a point on the plane, then calculate the intersection as before (see p_co assignment). # if 'fac' is between (0 - 1) the point intersects with the segment. # The factor of the point between p0 -> p1 (0 - 1) Return a Vector or None (when the intersection can't be found). P_no Is a normal vector defining the plane direction P_co Is a point on the plane (plane coordinate). # intersection functionĭef isect_line_plane_v3(p0, p1, p_co, p_no, epsilon=1e-6): With a Vector data type and operator overloading, it can be more concise (included in example below). Note: This example uses pure functions, without any dependencies - to make it easy to move to other languages.
Other details noted in the code-comments. Rotation for the object is 180º (if applicable for your aircraft) Set lighting to be inside Set shadow mode to interior only Make sure hi-res is checked Add two instances of G5Glass.obj and G5Px.obj each, one for each G5. You may want to return this too, because values from 0 to 1 intersect the line segment - which may be useful for the caller.

In the examples below (code for both is provided).Īlso note that this function calculates a value representing where the point is on the line, (called fac in the code below). Where the plane can be either a point and a normal, or a 4d vector (normal form),
And trying to edit by hand is beyond my capabilities.Here is a Python example which finds the intersection of a line and a plane.

(By the way, my computer crashes when I try to open Blender on it, so that isn't an option. The JD340-500 Airliner is a simulation software add-on for X-Plane 11 simulator of long- range wide-body passenger jet airliner 3D Model External Cockpit and Cabin 3D objects modelled and animated. So, my question is, does anyone familiar with both SU and X-Plane know of an alternative: a way to achieve my goal without spending money on another program? I could switch to AC3D as my modeling program, but I've already invested a lot of time in learning SketchUp and would rather not switch. I don't mind spending the 80 bucks for AC3D, but it seems a shame when only one use is envisioned. The workaround is to create the model in SketchUp and then import it into a program like AC3D, create the animation, and then go from there to X-Plane. The problem is that currently (according to X-Plane experts) SketchUp models cannot be exported to X-Plane with the SketchUp animation intact. Sometimes, I would like to animate an object so it works in X-Plane: an arresting tail hook that goes down and up or a canopy that opens and closes, for example, when a button or key is pressed in X-Plane. Therefore, my question is very specific, and I hope there are some X-Planers who might read this. I use SketchUp 8 to create models that I then export as X-Plane objects (using a plug in) and integrate with the actual aircraft in X-Plane Plane Maker.
