Microsoft Direct3D is a low-level graphics application programming interface (API) that enables you to manipulate visual models of 3-dimensional objects and take advantage of hardware acceleration, such as video graphics cards. It can be disabled by manipulation of Registry keys in Windows operations systems.
You can't replace Direct3d with OpenGL because it's part of your computer. However you can run OpenGL programs or games by downloading and installing a program called GLDirect. This program allows you to run OpenGL-based games and other applications using your graphics card's DirectX drivers.

The new market for 3D accelerators and 3D acceleration features has spawned a large crop of 3D video cards with varying capabilities. There are several different approaches that are taken to providing a system with 3D capabilities. While the available cards and technologies are changing rapidly, you will generally find that the cards on the market break out as follows: * 2D Only (Conventional) Cards: These are regular video cards that do not incorporate any special 3D acceleration functions. Usually these are either older cards, or newer cards that are optimized for 2D performance. When using a card of this type, it is necessary to pair it with a 3D card to obtain 3D acceleration functions. * Dedicated 3D Cards: These are accelerators that are designed only for 3D hardware functions. Since they do not do conventional 2D acceleration, they need to work with a 2D card in most cases to deliver good 2D+3D performance. Most of the higher-quality 3D cards are of this variety. They typically use a feature connector to connect directly to the 2D card. This lets the 3D card perform its acceleration functions to provide a video stream without requiring its own RAMDAC or bus control logic. This is generally the best solution for high-end graphics but it incurs the cost of two video cards. * Combination 2D+3D Cards: In an effort to tackle the cost problem of using an additional, separate card for 3D acceleration, many companies are developing cards that perform both 2D and 3D functions. For many users, this is a good, cost-effective compromise. Most of these cards provide from moderate to good 2D performance, and support for some to most of the 3D acceleration features. However, like most compromises, these cards typically don't provide the level of performance or feature support that dedicated 3D cards do. It is important to research these cards well, since many of them support only a small subset of the 3D acceleration features found on 3D cards.

because you downloaded it and (depends) on the system you downloaded it for or it could mean you need the latest version of Direct3D.
download the BitDefender and turn it into game mode so no problems related to the game will happened, but if problems persists, run dxdiag, then enable directx acceleration and the others(like direct3D and apg texture...) at the Display Tab...
Use SwiftShader 2.01 mrabhinavraj,inc
Vertex and pixel (or fragment) shaders are shaders that run on a graphics card, executed once for every vertex or pixel in a specified 3D mesh. They operate in the context of interactively rendering a 3D scene, usually using either the Direct3D or OpenGL API.
Well even if it runs minecraft, terraria doesnt have the same requirements. Like for one thing check if your system has Direct3D. Just go to steam.com and search for terraria and go onto the page and look down near the bottom (thats the requirements :D)
