windows11で、sketchup6 その51

概要

windows11に、sketchup6を入れてみた。
rubyで、3Dを書く。
カメラをアニメーションするプラグイン、見つけたので、やってみた。

サンプルコード

require 'sketchup.rb'


class ViewSpinner
	def initialize
		model = Sketchup.active_model
		view = model.active_view
		camera = view.camera
		@target = model.bounds.center
		@up = Geom::Vector3d.new(0, 0, 1)
		@distance = camera.eye.distance @target
		@zmin = @target.z
		@zmax = @zmin + @distance
		@dz = @distance / 300
		@z = @zmin
		@angle = 0
		@frame = 0;
		@startTime = Time.now
		Sketchup::set_status_text($exStrings.GetString("FPS"), 1)
	end
	def nextFrame(view)
		@frame = @frame + 1
		totalTime = Time.now - @startTime
		fps = 1
		if (totalTime > 0.001)
			fps = @frame / totalTime
		end
		fps = fps.to_i
		Sketchup::set_status_text(fps, 2)
		a = @angle * Math::PI / 180.0
		x = @target.x + (@distance * Math::sin(a))
		y = @target.y + (@distance * Math::cos(a))
		eye = Geom::Point3d.new(x, y, @z)
		view.camera.set(eye, @target, @up)
		@angle = (@angle + 1) % 360
		view.show_frame
		@z += @dz
		if (@z > @zmax)
			@z = @zmax
			@dz = -@dz
		elsif (@z < @zmin)
			@z = @zmin
			@dz = -@dz
		end
		return true
	end
	def stop
		Sketchup::set_status_text("", 1)
		Sketchup::set_status_text("", 2)
	end
end 

def spinview
	Sketchup.active_model.active_view.animation = ViewSpinner.new
end

if (not file_loaded?("animation.rb"))
	add_separator_to_menu("Camera")
	animation_menu = UI.menu("Camera").add_submenu("Animations")
	animation_menu.add_item("Spin View") {
		spinview
	}
	animation_menu.add_item("Stop Spinning") {
		Sketchup.active_model.active_view.animation = nil
	}
end

file_loaded("animation.rb")

以上。
