explosion-experiments Houdini export to Blender for shading and rendering Bellergy RC 2022-01-27 | The abstract explosions were created on Houdini. It used the pyro solver to create a smoke simulation and then used "Pop Advect by volumes" to convert the smoke volume to particles. Finally, export the particles to Blender for shading and rendering.It is a project to test how to export particles with attributes (e.g. velocity, colors) to Blender.Download the Houdini file here (support Houdini 18-19):drive.google.com/file/d/16zjyqtLKWuxZXEtiA3MpwRiU0i6ciEqi/view?usp=share_link

Parrot DISCO 28km long range flight journey with DISCO4G mod Bellergy RC 2019-02-18 | 28km, the farthest distance currently. The equipment used is as follows:- Parrot DISCO- DISCO4G softmod (Thanks for active and friendly community uavpal.slack.com)- Panasonic NCR18650B Li-ion 3S2P Battery - HUAWEI E3372 (4G USB)
Disco4G 24km Long Range Flight with 3S2P Li-ion battery Bellergy RC 2019-01-08 | This time, I tried 24km flight. It only used about 50% battery. Next time I can plan for a 40km flight.I change the Disco's BATTERY_PERCENTAGE_TABLE_VOLTAGE in config file. It can provides more accurate li-ion battery usage data now.This time I changed the 4G modem antenna angle, but the result was even worse. I lost connection 3 times on the flight. The reconnection took 1.5 to 2.5 minutes.The Insta360 let me control the camera angle after flight. It is useful when i lost the signal.The Parrot Disco installed:- Disco4G softmod- 3S2P NCR18650B Li-ion battery- HUAWEI E3372h modem- Insta360 One X camera
A little crash, but lost my Mavic 2 Bellergy RC 2018-12-29 | A very common mistake, I lost my Mavic 2 while on vacation.It crashed in the trees. The location was hard to reach. I searched it a hour but no result. I have to leave it because of travel schedule.The video is DJI Go app realtime cache, so the resolution is not high.
Shoot 4K VR aerial video with Parrot Disco and Insta360 One X (long flight 6.7km) Bellergy RC 2018-12-19 | I installed Insta360 One X on the bottom of Parrot Disco. It is the result of 4K VR video.The soft stabilizer of Insta360 One X is awesome. The Parrot Disco swings in the air, but the picture is very stable.At the same time, you can see how hard the Parrot Disco works and it is very interesting.In my other video, you can see how Insta360 is installed into Disco.youtu.be/5pgjx5-cwyYThe Insta360 with battery is weight 115g.

Parrot Disco installed Insta360 One X and disco4G (6.7km flight) Bellergy RC 2018-12-16 | I can't believe that Parrot Disco can shoot video so freely. When I did this test, the effect was better than expected. Awesome!"Shooting"I installed Insta360 One X on the bottom, just like many other multi-copter cameras. Now I can shoot a lot of angles that I could only get in an multi-copter cameras. Because it is a 360 degree panoramic video, I no need to distract the video angle and view during flight. Through post-production, I can find the angles I like in front of my computer. Please pay attention to the screen (10:20), the eagle that rushed to the front was discovered when the post-production. Due to the speed, it is impossible to make a live capture. "Disadvantage"1. Insufficient resolution, this film is HD (1920x1080), we can't render it to 4K;2. When the wind is strong, flying at high speed or climbing, the video will have a jello effect, which cannot be eliminated by post-production (00:33);3. Post-production will take more time;4. 360 video files are larger, and the computer's functional requirements are higher "Landing"Since the camera is below, the Parrot Disco has no landing gear. A flat landing may damage the Insta360. So the place with the long grass is found to be landing, and the result is satisfactory.

北海道 丸瀬布 山彦の滝 航拍 Bellergy RC 2016-07-12 | 北海道航拍之旅第10天：山彦の滝 28米高的瀑布，隱藏在山林之中。航拍機在林頂往下望，完全看不見瀑布的踪影。在下面，人可以走進瀑布的背面，我稱之為3D的瀑布。瀑布不算很大，但很別緻，經過丸瀬布的話可以一遊。停車場住山上走約五分鐘便到。北海道之旅自駕遊Blog：http://dollergy.net
北海道知床フレペの滝 航拍 Bellergy RC 2016-07-11 | 北海道航拍之旅第9天：由於浪大，原來的行程「知床觀光船」被迫折返。在船上看到一個很有氣勢的斷崖，上岸後就在Google Map上找找有沒有陸路可以去到，原來就是知床八景之「フレペの滝」。廣闊的觀景區內空無一人，腳下是百米斷崖，對望燈塔與藍天，真是一個航拍的絕景哦！北海道航拍之旅第4天：礼文島是我旅程中最期待的地方，美麗的自然風景，人不多，很適合航拍。但天氣不似預期，大風得連人也站不穩，航拍就更不用提了。這條片是禮文島的東南端所拍的，地名是知床。那裡風還是很大，飛出去不知能不能回來。但太美了，冒險也得一試。正因為天氣不好，拍出來好有氣勢。還是很喜歡禮文島，這裡我一定會再來的！I will be back!北海道之旅 自駕遊Blog：http://dollergy.net

航拍 啟德郵輪碼頭與海洋贊禮號 Ovation of the Seas Bellergy RC 2016-06-26 | 航拍啟德郵輪碼頭與海洋贊禮號好奇怪的，郵輪碼頭平台兩邊種了好些植物，使遊人不能接近欄杆。有些想和郵輪影相的人只有踩過植物，而管理公司就多加些警告牌，再加繩保護。為什麼變成這樣？上平台，想看看郵輪是常識的吧。 （哦，注意，此片不是在平台上拍的。）Aerial video of Kai Tak Cruise Terminal with Ovation of the Seas Cruises.

北海道 サロベツ湿原 航拍 Bellergy RC 2016-06-11 | 北海道航拍之旅第3天：這次帶drone去旅行的旅程中，唯一一次有人「阻止」的飛行。在飛行完結後，把航拍機拿回車上的不到50米的距離中，有位管理員女仕走出來，很有禮地對我說了一段日文，我估計是不可放航拍機之類的吧。我也有禮地對她說我現在就走了，她還向我說對不起，過程中沒有不快。接下來的飛行我也盡量不在有管理的地方起飛，便沒有發生任何問題了。北海道之旅旅遊Blog：http://dollergy.net
