kandi X-RAY | ROYGBIV Summary
ROYGBIV is a WebGL engine for motivated programmers who do not have the budget for buying fancy 3D models or licensing a popular engine but still want to make 60 FPS web applications for both mobile and desktop. It is being developed by one of such programmers on top of low level THREE.js features for the graphics and CANNON.js for physics. It is named after this Boards of Canada track.

QUESTION
Is it possible to set the lower and/or upper parts of a colorbar based on ranges of values? For example, given the ROYGBIV colormap below and optionally an offset
and a range
value, I'd like to change the colors below offset
and/or above range
. In other words, suppose offset = 20
and range = 72
, I'd like to color all the values less than or equal to 20 in black and all values greater than or equal to 72 in white. I'm aware of the methods set_under
and set_over
, but they require changing the parameters vmin
and vmax
(as far as I know), which is not what I want. I want to keep the original minimum and maximum values (e.g., vmin = 0
and vmax = 100
), and only (optionally) change the colors of the extremities.

Answered 2020-Jun-09 at 22:14I found one way to do it using ListedColormap
as explained here. The basic idea is to obtain the RGBA lists/tuples of the colors in the LinearSegmentedColormap
object (numpy
array) and replace the first or last few lists with replicates of the desired color.
It looks something like this:
QUESTION
I'm trying to write a simple program that asks for input of a favorite rainbow color first letter (ROYGBIV) and print the value of the letter given. For example, if user input is "R", the program will print "Red". I tried to use dictionaries but I couldn't get it to work. Could you help me correct my mistakes?

QUESTION
I'm designing a Spring Boot REST API that will be backed by MySQL. It has occurred to me that I want, effectively, two separate models for all my domain objects:
- Model 1: Used between the outside world (REST clients) and my Spring REST controllers; and
- Model 2: The entities used internally between by Spring Boot app and the MySQL database
For instance I might have a contacts
table for holding personal/contact info:
ANSWER
Answered 2017-Apr-07 at 13:47You can actually accomplish this with just one model and I think it is the easiest way if you are just looking for hiding fields, custom formatting, simple transformation of attributes etc. Having two models require transformation from one model to another and vice-versa which is a pain. Jackson provides a lot of useful annotations which can be used to customize the output. Some of the annotations that can be useful for you are listed below
@JsonIgnore
- ignore a field/attribute. You can hide your id field using this annotation.
@JsonInclude
- Can be used to specify when a field should be present in output. For eg: Whether a field should be present in output if it is null
@JsonSerialize
- You can specify a custom serializer for an attribute. For eg: You have an attribute 'password' and you want to output password as '****'.
@JsonFormat
- You can apply a custom format to a field. This is very useful if you have date/time fields
@JsonProperty
- If you want to give a different name for your field in your output. For eg: You have a field 'name' in your model and you want to display it as 'userName' in the output.
