The 3D graphics rendering pipeline consists of 4 main stages: 1) vertex processing, 2) rasterization, 3) fragment processing, and 4) output merging. In vertex processing, transformations are applied to position objects in the scene and camera. Rasterization converts vertex data into fragments and performs operations like clipping and scan conversion. Fragment processing handles texture mapping and lighting. Output merging combines fragments and uses the z-buffer to remove hidden surfaces when displaying the final pixels.

“3D Turtle Graphics” by using a 3D PrinterIJERA Editor
When creating shapes by using a 3D printer, usually, a static (declarative) model designed by using a 3D CAD system is translated to a CAM program and it is sent to the printer. However, widely-used FDM-type 3D printers input a dynamical (procedural) program that describes control of motions of the print head and extrusion of the filament. If the program is expressed by using a programming language or a library in a straight manner, solids can be created by a method similar to turtle graphics. An open-source library that enables “turtle 3D printing” method was described by Python and tested. Although this method currently has a problem that it cannot print in the air; however, if this problem is solved by an appropriate method, shapes drawn by 3D turtle graphics freely can be embodied by this method.
Global Situational Awareness of A.I. and where its headedvikram sood
You can see the future first in San Francisco.
Over the past year, the talk of the town has shifted from $10 billion compute clusters to $100 billion clusters to trillion-dollar clusters. Every six months another zero is added to the boardroom plans. Behind the scenes, there’s a fierce scramble to secure every power contract still available for the rest of the decade, every voltage transformer that can possibly be procured. American big business is gearing up to pour trillions of dollars into a long-unseen mobilization of American industrial might. By the end of the decade, American electricity production will have grown tens of percent; from the shale fields of Pennsylvania to the solar farms of Nevada, hundreds of millions of GPUs will hum.
The AGI race has begun. We are building machines that can think and reason. By 2025/26, these machines will outpace college graduates. By the end of the decade, they will be smarter than you or I; we will have superintelligence, in the true sense of the word. Along the way, national security forces not seen in half a century will be un-leashed, and before long, The Project will be on. If we’re lucky, we’ll be in an all-out race with the CCP; if we’re unlucky, an all-out war.
Everyone is now talking about AI, but few have the faintest glimmer of what is about to hit them. Nvidia analysts still think 2024 might be close to the peak. Mainstream pundits are stuck on the wilful blindness of “it’s just predicting the next word”. They see only hype and business-as-usual; at most they entertain another internet-scale technological change.
Before long, the world will wake up. But right now, there are perhaps a few hundred people, most of them in San Francisco and the AI labs, that have situational awareness. Through whatever peculiar forces of fate, I have found myself amongst them. A few years ago, these people were derided as crazy—but they trusted the trendlines, which allowed them to correctly predict the AI advances of the past few years. Whether these people are also right about the next few years remains to be seen. But these are very smart people—the smartest people I have ever met—and they are the ones building this technology. Perhaps they will be an odd footnote in history, or perhaps they will go down in history like Szilard and Oppenheimer and Teller. If they are seeing the future even close to correctly, we are in for a wild ride.

The Building Blocks of QuestDB, a Time Series Databasejavier ramirez
Talk Delivered at Valencia Codes Meetup 2024-06.
Traditionally, databases have treated timestamps just as another data type. However, when performing real-time analytics, timestamps should be first class citizens and we need rich time semantics to get the most out of our data. We also need to deal with ever growing datasets while keeping performant, which is as fun as it sounds.
It is no wonder time-series databases are now more popular than ever before. Join me in this session to learn about the internal architecture and building blocks of QuestDB, an open source time-series database designed for speed. We will also review a history of some of the changes we have gone over the past two years to deal with late and unordered data, non-blocking writes, read-replicas, or faster batch ingestion.

15. Camera control 2
For dynamic and more flexible camera control active the
SpaceBall on the toolbar.
A ball with its 3 main arcs is drawn
on top of the geometry. Moving the
mouse near an arc will active it. Any
movement of the mouse with the
left mouse button pressed will move
the arc and thus, the camera.

16. Camera control 3
For more flexibility you can grab the SpaceBall even at
points that are not placed on an arc. For this you have
to keep the Shift key pressed together with the left
mouse button.
On slow graphics cards this operation might slow down.
Keeping the Ctrl key pressed in addition will reduce the
level of detail shown during the movement!

21. More on rendering options
There are several other rendering options:
Aliasing: Softening of jagged contour lines. High-end
gfx cards can do this “on-the-fly” to some extent.
Parallel projection, allows you to obtain flat looking images. The look
is similar to 2D sections if the camera is set to the correct position.

26. Searching in the CSG tree
Several search refinements options are available. The options given
above will find every node which has a material assignment that partially
matches “ai” in its name. In our case we will find all nodes with a
material assignment of “Air”. Pressing the < and > key automatically jumps
to the respective node in the CSG tree.
If requested regular expressions are available for more complex searches.

27. Saving images & geometries…
The currently visible geometry can be saved to an image by selecting
“Save Image” from the “File” menu, or it can be copied to the clipboard
via “Edit” – “Copy to clipboard” for immediate insertion in other Windows
applications.
The geometry can be exported to different raytracing packages via “File” -
“Export” - “3D objects”. These packages do not support interactivity but
supply photorealistic images.

28. Saving images & geometries…
One supported file format is VRML. You
can pass these files on to collaborators
who can inspect them in a web browser
using any freely available VRML plugin.
(e.g. CORTONA). They do not need
SimpleGeo!
For ray-tracing packages only regions
that are currently visible are saved to
avoid cluttering.
