In the middle of 2017, Dreamview received one private inquiry for a summer house retrofit project. The mission is simple: solar panel to power the summer house (no connection to the grid) build a battery system to power the house when there is no sun remote monitoring (if. About Dreamview Dreamview Creamery is located on the hills above Raglan and overlooks the Whaingaroa Harbour and Tasman sea. Owned by the Hill family, we have farmed the rugged 300 acre property for 20 years and began our farming journey at Dreamview with a 250 cow dairy farm.
The Dreamview web server is provided by the dreamview node(A node is an executable in ROS concept). Before accessing the Dreamview page, you need to build the system(including dreamview node) within the docker container following the guide. Once built, dreamview node will be started after the step bash scripts/bootstrap.sh
.
So if you can not access Dreamview, please check:
- Make sure you have dreamview process running correctly. In the latest version,
bash scripts/bootstrap.sh
will reportdreamview: ERROR (spawn error)
if dreamview fails to start. For early version, please check with command:supervisorctl status dreamview
orps aux | grep dreamview
. If dreamview is not running, please refer to How to Debug a Dreamview Start Problem or go to Dreamview does not load successfully. - Make sure the address and port are not blocked by the firewall.
- Make sure you’re using :8888 instead of localhost:8888 if you are not accessing the Dreamview page through the host machine.
Dreamview does not open up if I install more than 1 version of Apollo?
This issue occured because of port conflict error.Even though you setup two different docker environments, both of them are still trying to use port 8888 on your machine, therefore causing a port conflict issue. If you’d like to run both versions at the same time, please make sure different ports are set.
To do so,
- Open
dreamview.conf
file under modules/dreamview/confadd--server_ports=<PORT_NUMBER>
to the end of the file.Ex:–flagfile=modules/common/data/global_flagfile.txt–server_ports=5555 - Restart apollo

This way, dreamview can be accessed from http://localhost:

Dreamview is too slow. How do I resolve it?
If you feel Dreamview is taking too long to load/work, please run both the WebGL reports. If there are any missing drivers, please install them
How to draw anything in DreamView (e.g. an arrow)
Dreamview uses https://github.com/mrdoob/three.js as graphics library. You can modify the frontend code to draw an arrow using the corresponding API of the library. After that you need to run a ./apollo.sh build_fe
to compile.
How can I test planning algorithms offline?
Use dreamview and enable sim_control on dreamview to test your planning algorithm.
Adding a new point of interest permanently in the Dreamview interface
There’s a default_end_way_point file for each map to specify point of interest, you can refer to the following file.
What’s the function of sim_control in the backend of dreamview
It simulates a SDC’s control module, and moves the car based on planning result. This is a really convenient way to visualize and test planning module
How do I turn on Sim Control?
Purpose of sim control: drive the car based on the planning trajectory. Good for debugging planning algorithms.
Apollo 2.5 or after: simply turning on the SimControl switch as seen in the image below:
Apollo 2.0 or older: you would need to enable the sim control manually, which can be performed as follows:
- Open
modules/dreamview/conf/dreamview.conf
- Add “–enable_sim_control=true” to the second line of the file
- Restart apollo using our bootstrap script
Please note, planning and routing modules (see image below) should be ON while using SimControl. To navigate the ego-car, select either “route editing” or “default routing” from the side bar to define a route. You can turn the sim_control on and off from the toggle. However, a new routing request is needed each time the sim_control is restarted.
Dreamview does not start even though the build is successful
There are 2 steps to deducing this issue:
- Identify if the issue is due to pcl lib through gdb: this can be done by finding the coredump file under
/apollo/data/core/
with name core_dreamview.$PID.If you see logs like:```@in_dev_docker:/apollo$ gdb bazel-bin/modules/dreamview/dreamview data/core/core_dreamview.378GNU gdb (Ubuntu 7.7.1-0ubuntu5~14.04.3) 7.7.1Copyright (C) 2014 Free Software Foundation, Inc.License GPLv3+: GNU GPL version 3 or later http://gnu.org/licenses/gpl.htmlThis is free software: you are free to change and redistribute it.There is NO WARRANTY, to the extent permitted by law.
