windows11で、sketchup6 その57

概要

windows11に、sketchup6を入れてみた。
rubyで、3Dを書く。
練習問題、やってみた。

練習問題

rubyスクリプトでカメラを動かせ。

サンプルコード

def camera_vp_targ
	model = Sketchup.active_model
	view = model.active_view
	camera = view.camera
	eye = camera.eye
	vx = eye.x
	vy = eye.y
	vz = eye.z
	target = camera.target
	tx = target.x
	ty = target.y
	tz = target.z
	vfovdeg = camera.fov
	w = Float(view.vpwidth)
	h = Float(view.vpheight)
	vfovrad = vfovdeg * Math::PI / 180.0
	f = (h / 2) / Math.tan(vfovrad / 2.0)
	hfovrad = 2.0 * Math.atan2((w / 2), f)
	hfovdeg = hfovrad * 180.0 / Math::PI
	prompts = ["Position X", "Position Y", "Position Z", "Target X", "Target Y", "Target Z", "angle focal"]
	values = [vx, vy, vz, tx, ty, tz, hfovdeg]
	results = inputbox prompts, values, "Point de vue Camera / Mire"
	vx, vy, vz, tx, ty, tz, hfovdeg = results
	eye.x = vx 
	eye.y = vy 
	eye.z = vz 
	target.x = tx
	target.y = ty
	target.z = tz
	up = camera.up
	up.set!(0.0, 0.0, 1.0)
	camera.set eye, target, up
	hfovrad = hfovdeg * Math::PI / 180.0
	f = (w / 2) / Math.tan(hfovrad / 2.0)
	vfovrad = 2.0 * Math.atan2((h / 2), f)
	vfovdeg = vfovrad * 180.0 / Math::PI
	camera.fov = vfovdeg
end 

以上。
