How to display full 3D region?

Answers to an earlier posting, ConvexHullMesh inconsistency, have let me construct a particular 3D region by intersecting a pyramid with a halfspace:

Rint = RegionIntersection[Rhalfspace, RPyramid] 

The construction is correct, and the region displays like this upon executing the above command:


Rint


The slanted plane is (correctly) caused by `Rhalfspace`. The two vertical planes are caused by some type of plotrange clipping. My question is simple:

Q. How do I display the full region?

I’ve tried RegionPlot3D, DiscretizeRegion, but nothing I try allows me to e.g., use PlotRange. I am missing something basic about how to convert a region to a 3D graphics object.

I know I should include code for experimentation, but perhaps there is just a simple generic method to convert a 3D region to Graphics3D so that I can use the options to Graphics3D.

How do I create a column and display user data from custom registration field

Our registration form has a custom field for Hospital Name. In SQL wp_usermeta the meta_key is user_registration_hospital. I have tested a number of snippets in the functions.php file to add a "Hospital" column to the Users admin table, all of which work. This is one of the snippets that adds the Hospital column:

function add_user_columns($  column) { $  column['hospital'] = 'Hospital';  return $  column; 

} add_filter( ‘manage_users_columns’, ‘add_user_columns’ );

What code do I need to add to the functions.php file to have the Hospital data from wp_usermeta populate the Hospital column?

Display `Table` output as a 3D bar chart

Create a simple function with arguments {i,j}, and make a Table for an array of values. For example:

f[i_, j_] := i*j;  data = Table[f[i, j], {i, 1, 25}, {j, 1, 25}] 

I want to create a 3D ‘bar chart’ of data – i.e., a plot that has a column of height f[i, j] at each Cartesian point {i,j} (ideally a block-shaped column with width and depth 1 centred on {i,j}. It sounds dead simple…

But ListPlot3D creates a meshed surface, not a series of columns, and I can’t see an option to change this. And Histogram3D doesn’t accept the format of data, and in any case I can’t get my head around how it generates 3D information from pairs containing only 2 data points each – it’s set up for data sampling, not plotting.

Suggestions?

how to create user profile pages and display them based on users roles

Example: I have a website with 3 different user roles (amongst others): *developers *designers *contributors

I would like to have profile pages for users and would like to be able to display users on pages based (filtered) by their role. Hope this is clear. I have researched quite a few membership plugins and found that they are just bloated with features and ended up with TMI and no answers/solutions, so if you can help I would appreciate it. Do you know of any plugins suitable of doing that?

Thanx in advance

Woocommerce Booking – Display selected block amount or duration

I am using Woocommerce Booking plugin and I would like to display the number of blocks a user is about to book.

eg:

  • Create bookable product with 30 minute blocks, min:1, max;4
  • User selects start:9:00, end:10:30
  • Front end displays calculated price and “3 Blocks”

Is this possible? and how would I go about doing this? Is there a hook or is it a template change?

Display all videos on separate page from certain ACF field

I am using Elementor and ACF. Using ACF I created oEmbed field for adding videos for each post. Idea is to show all uploaded videos on separate page.

So on separate video page I want to display all videos related to this ACF oEmbed field from all posts.

I’ve tried with Elementor Custom Skin plugin, but two problems. Video UI is not like on Vimeo and another problem is display empty fields, so I have empty div elements, but I’ve add conditionals logic and still problem.

Floating point binary number to a 7 segment decimal display

I have covered floating point (32 bit) conversion from float to decimal and decimal to float. I am happy with the theory and I have created a conversion tool in Excel VBA which works just fine following the IEEE754 , so I am happy with theory. Also happy with add, sub , mult , div of 32 bit floating point binary numbers. What I cannot understand or find anywhere online is the answer to this simple question. How do computers / calculators do the final conversion from the floating point binary number onto a display. For eaxmple , I have built a BCD to decimal converter using Logisim (combinational logic gates) and I have built a Binary to Decimal converter in Logisim using the Double Dabble algorithm si I can see how these can display on a set of 7 segment displays but how does the number (0 10000001 01 00 11 00 11 00 11 00 11 00 11 0) which is the floating point binary for decimal number 5.2 actually get converted using logic circuits.

WordPress Plugin to display a list of input fields which are visible to everyone?

I am looking for a plugin/workaround recommendations. I am sorry if the title was not descriptive enough, this is the best I could think of. Any edit suggestion is welcome.

I want to display a list of editable text fields, which are updated by any visitor, and all updates are live and public to everyone else. The submitted fields may or may not be editable anymore.

So, once a visitor visits the page, there will be a list of empty blanks/fields, short text fields for instance. They will fill in their name and their details, then submit. All other visitors will see that this field is taken/filled.

The reason is that there will be a list of offerings, and the link will be distributed among participants only, each participant can fill a “slot” with their details after seeing which slots are available.

I don’t need any extra validation or complexity. Logging in is not required.

  • Preferably free, reasonably paid solutions are accepted, too.

Display list of posts from taxonomy term, but display the latest post featured image

I’m trying to do a page where all posts from a custom post type list, divided by their taxonomy terms and having a big photo on top of the list (latest featured image from said term). Right now I have the following code, but it displays the wrong images (each term should show latest post’s featured image, and I’m not even sure why the images are just random, even in the wrong term):

<section id="" class="">  <?php      }     wp_reset_query();   $  tax = 'technology-category';      $  terms = get_terms( $  tax ,array(          'orderby'    => 'ID',         'order'      => 'ASC',         'hide_empty' => 0,     ));      //Loop throug each taxonomy terms,      foreach ( $  terms as $  term ) {          //Query argument for post     $  args = array(              'post_type' => 'technology', // Or Custom Post Type,              'order' => 'DESC',              'orderby' => 'date',             'taxonomy' => $  tax,             'term' => $  term->slug, // Query posts for each term based on term slug         );         $  query = new WP_Query( $  args );          $  posts = $  query->get_posts();          ?>  <div class="container-fluid tech-cat-item py-5">     <div class="container">     <div class="row align-items-center pb-3">     <div class="col-1">     <img class="img-fluid" src="<?php echo z_taxonomy_image_url($  term->term_id); ?>"> </div> <div class="col-11">     <h3><?php echo $  term->name;?></h3> </div> </div> <?php //Do query to get image?        $  ga_item = array(             'post_type' => 'technology',               'order' => 'DESC',              'orderby' => 'date',             'taxonomy' => $  tax,             'term' => $  term->slug,              'posts_per_page' => '1', //just one because only need the latest post's featured image );        $  ga_query = new WP_Query( $  ga_item );         $  ga_posts = $  query->get_posts();     if ( $  ga_query->have_posts() ) {     while ( $  ga_query->have_posts() ) { $  ga_query->the_post(); ?>     <div class="row ga-panel py-5">     <div class="col-12">         <?php          $  ga_url = get_the_post_thumbnail_url($  post->ID,'full'); ?>         <img class="img-fluid ga-img" src="<?php echo esc_url($  ga_url);?>">     </div>     </div> <?php } } wp_reset_query(); ?>     <div class="row">         <?php          if ( $  posts ) {          foreach ( $  posts as $  post ) { ?>              <div class="col-4 ga-links">                 <a href="<?php the_permalink( $  post->ID ); ?>" data-swap="<?php echo esc_url($  ga_url);?>" > <?php echo $  post->post_title; ?></a>             </div>          <?php                     }         }        ?> </div> </div> </div>   <?php  }  wp_reset_query(); ?>                      </section>
